Location: Woodland Waters (South Lincolnshire, UK)
From: 2008-02-09 19:55 UT

Equipment: Antares 905
Lomo Lubitel 166B
Meade 10x50 Binoculars
Naked Eye
Notes:

Joined John and Kevin at Woodland Waters for an observing session. Not the best of nights, some thin cloud and contrails sticking around, also quite damp and a little hazy at times.

I brought my Antares 905 and John brought his Evostar 150.

Checking for Comet Holmes

From: 2008-02-09 20:10 UT
To: 2008-02-09 20:20 UT

I started out the session by seeing if comet Holmes was still visible to the naked eye. Given that the last time I saw it it appeared to be about the same brightness as the Double Cluster, and given that I could see the Double Cluster, I guessed I stood a chance of it was still of similar brightness to the last time.

After looking carefully for a couple of minutes I decided that it must be even fainter than the last time. I then grabbed my 10x50 binoculars and had a look in the general area around Algol and I pretty much saw it right away. Very faint and very diffuse. Only just brighter than the background sky. If I wasn't looking for it I probably wouldn't even have noticed it.

Started a Star Trail

Time: 2008-02-09 20:33 UT

I set the Lomo Lubitel 166B up on a tripod and started a star trail.

The camera was loaded with Ilford FP5+ 400 (120 roll film), the aperture was set to f8. Like the last time I tried this this was an experiment. This time I was interested to see what results I'd get with a faster film.

The camera was roughly pointed in the general direction of the Pleiades (M45) and the Hyades in Taurus.

Saturn

From: 2008-02-09 20:35 UT
To: 2008-02-09 20:45 UT

Had a brief view of Saturn via John's 'scope. Much like my last observation the view was very "soft" with no real detail visible. No shadow of the rings on the planet could be seen although, once again, I did get the impression that the rings were two separate and detached objects either side of the planet.

Titan was nicely visible.

Mars

From: 2008-02-09 20:47 UT
To: 2008-02-09 21:00 UT

Had a look at Mars via the 905 with the 6mm eyepiece and the 2x barlow. Just like always, I couldn't get any detail out of the planet. One thing I did notice though was that there was a definite hint of a gibbous phase. The planet did seem to be "taller" than it was "wide".

Stopped the Star Trail

Time: 2008-02-09 21:01 UT

Stopped the star tail I'd started earlier.

Taurus Star Trail

M1

From: 2008-02-09 21:15 UT
To: 2008-02-09 21:40 UT

Decided to have a look at M1 given that I'd not taken a look in over a year. With the 905 and the 25mm eyepiece it was very easy to find and, unlike previous observations, seemed to stand out really well. Despite the conditions during the evening (which were less than ideal) I'm pretty sure it was a better view than the one I once had via the 130M. Although it was the usual indistinct light patch it appeared to contrast with the background sky better than I'm sure I've seen it before.

M65 and M66

From: 2008-02-09 21:55 UT
To: 2008-02-09 22:05 UT

Had a look at M65 and M66 via John's 'scope and his 42mm eyepiece. Just two very faint patches of light, mostly needing averted vision to see them. It was impossible to make out any distinct shame or to say what their relative orientations were.

A break and a chat

From: 2008-02-09 22:10 UT
To: 2008-02-09 22:45 UT

Had a coffee and food break and a chat. Given that it was getting very cold and damp this was needed.

M95 and M96

From: 2008-02-09 22:50 UT
To: 2008-02-09 23:00 UT

Had a look at M95 and M96 via John's 'scope and his 42mm eyepiece. Just as with the previous view of M65 and M66 they appeared as two very faint patches of light, mostly needing averted vision to see them.

905 totally fogged up

Time: 2008-02-09 23:09 UT

I went to use the 905 and noticed that it was dripping with dew and that the main lens was totally fogged up. Decided to call it a night as far as the 905 was concerned.

Trying for the Eskimo Nebula

From: 2008-02-09 23:15 UT
To: 2008-02-09 23:35 UT

We spent some time using John's 'scope to try and locate the Eskimo Nebula but never managed to locate it. I made a note to check in some of my books and see how easy it should be to locate.

M3

From: 2008-02-09 23:40 UT
To: 2008-02-09 23:52 UT

Given that Canes Venatici was quite high up now we decided to have a look at M3 with John's 'scope. I first found it with my monocular to be sure of the location and then we got it in John's 'scope. With his 42mm eyepiece it was obvious that it was a globular cluster although no detail could be seen. Switching to his 15mm eyepiece we could see a hint of mottling in it giving the impression of a collection of starts without resolving any actual stars.

End of session

Time: 2008-02-09 23:55 UT

By 23:55 UT everything was terribly damp so we decided that it was time to call an end to the session.

Sun

From: 2006-12-16 12:20 UT
To: 2006-12-16 12:25 UT

Active area 930 was still visible although somewhat foreshortened due to getting closer to the limb of the Sun. Today I could only make out a single large spot. The penumbra around it was just about visible.

This was the first observation of 930 where I was unable to see it with the naked eye (via eclipse shades).

Location: Woodland Waters (South Lincolnshire, UK)

To: 2006-12-16 23:50 UT
Equipment: Antares 905

Notes:

Very clear and cold night. Arranged to meet up with John Turner at Woodland Waters to try it out as an observing location. I took along my Antares 905 and John brought his Sky-Watcher Explorer 130M mounted on an EQ5 mount.

A Leisurely View of Various Objects

From: 2006-12-16 19:00 UT
To: 2006-12-16 23:50 UT

We got to the observing location at around 19:00 UT to find reasonable clear skies with no sign of any cloud anywhere. Some time was spent finding a location and setting up and then the rest of the evening was spent chatting and having a leisurely view of random sights in the sky.

I started with a quick view of M42. Orion was still quite low at the time and the view wasn't very impressive. With the 32mm eyepiece and the 905 I could only just make out the glow of the nebula with averted vision. I decided to come back to it when Orion was higher.

Next I had a quick look at M45. I noticed that the seeing seemed very steady.

I then went on to have a look at M1. This was the first time I'd had a look at it in over a year and it was also the first time I'd observed it with the 905. The view was more or less the same as I remember from the last time — an indistinct patch of glowing sky that was best noticed with averted vision.

At 20:30 UT I saw a very bright and fast meteor travel north to south just below Taurus.

I then had a quick look at M36, M37 and M38 via the 905. All looked very clear and very steady with many individual stars visible. It was quite a different view from that that I've previously had in a binocular. With a binocular I'd previously noted that the clusters had the appearance of globular clusters but via the 905 it was very obvious that I was looking at open clusters.

At around 21:15 UT I returned to M42. By now Orion was higher and the view was much better. With the 905 and the 32mm eyepiece the nebula easily withstood direct vision. Quite a bit of detail was visible, it had quite a mottled appearance. I then dropped the 6mm eyepiece in the 905 and could easily pick out the trapezium.

During the next hour I kept going back to M42 and noted that the view kept improving as it got higher in the sky. Had it not been for the dampness (quite a bit of dew was forming) I'd probably have had a go at producing a sketch.

At around 22:23 UT Saturn was starting to rise above some trees near us. I had a quick look with the 905 and the 6mm eyepiece. The view wasn't that good due to it still being quite low, being viewed amongst the top branches of the trees and also due to some thin cloud started to get in the way. I could, however, easily make out the rings and a hint of the shadow of the rings. There was no sign of the Cassini Division. Titan was easily visible too.

Around 23:19 UT John suggested that I try and locate M81 and M82 in the 905. Using the 32mm eyepiece I pointed the 'scope at about the right location (working off 24 Ursae Majoris) and found them right away. The sight was far more impressive than I thought it would be. M81 had an elliptical appearance, as if I was seeing a galaxy partially tilted towards me, whereas M82 looked more like it was edge on and appeared to have a kink in it. The following evening I did some checking in a couple of books and the impression I had of them appears to perfectly fit the images.

At around 23:50 UT we started to pack up the equipment. All in all I'd say it was one of the best sessions I've had yet. While I didn't have any kind of observing plan, and while my notes weren't as detailed as they normally are when I observe alone, it was nice to share views and impressions with another observer. It was also nice to observe a largely unobstructed sky.

Notes:

Reasonably clear night but appearing a little unsteady at times. I was caught out by it, I wasn't expecting it to be clear. Having noticed in Starry Night that Uranus would be well placed for viewing from my garden I decided to pop out and see if I could view it.

Uranus

From: 2006-10-24 20:30 UT
To: 2006-10-24 21:20 UT

First off I used Starry Night to figure out exactly where Uranus was in relation to easily spotted star patterns. After I was happy that I'd be able to find it I went outside with the 10x50 binoculars and tried to track it down. I was surprised to find that I could see it with no problems whatsoever.

Uranus was near to, and down and to the right from, Lambda Aquarii. Lambda Aquarii was quite a fascinating object to see in itself given its vivid red colour. In relation to the surrounding stars Uranus, while obvious given that I knew where it should be, didn't stand out as being a planet. If I hadn't known what I was looking for and where I was looking for it I would simply have thought it was just another star.

Having seen it with the 10x50s I decided to get the Antares 905 out and have a look at it through that. After setting up the 905 I started out with the 25mm eyepiece and got Lambda Aquarii in the field and then centered on Uranus. I then worked my way up to the 6mm eyepiece, keeping Uranus in the center of the field of view as I went.

By about 20:50 UT I had Uranus and TYC5813-273-1 in the field of the 6mm. Even at this magnification I would have thought that I was looking at 2 stars if I hadn't already known one of them was a planet. Initially there was no hint of any kind of disc and I could detect no obvious colour.

The observation probably wasn't helped by the fact that, at the elevation of Uranus, the sky was a little murky and sometimes quite unsteady.

After some more viewing, especially when comparing it with TYC5813-273-1, I began to detect that Uranus wasn't a point-source but was actually a very small disc (at least I think I could see that, I don't think it was wishful thinking).

Around 21:08 UT, after scanning the area around Uranus and memorising some of the closer stars, I went back into the office to double-check what I'd seen with Starry Night. The main feature that stood out was two starts, sort of close together, just south of Uranus. I could see them in Starry Night (they were TYC5813-519-1 and TYC5813-814-1) and this confirmed that, without a doubt, I was looking at Uranus.

I also noticed in Starry Night that TYC5813-789-1 was very close to Uranus but I never did manage to see it through the 'scope.

After doing the above checking and after memorising the general pattern of starts around Uranus, at around 21:15 UT, I went back out and put the 10mm eyepiece in the 905 and checked everything again. Everything matched and there was no doubt that I'd found Uranus.

Random viewing

From: 2006-10-24 21:25 UT
To: 2006-10-24 22:15 UT

Given that I was out with the 905 and given that the sky wasn't too awful I decided to stay out a bit longer even though I managed to achieve my aim for this session. Because I didn't really have any other sort of plan I decided to just randomly sweep around the sky looking at whatever turned up or took my fancy.

First off I tried to have a look at M31 with the 905. Annoyingly, because it was so far overhead, I couldn't get the 905 in a position where I could view it, the mount kept getting in the way. So, instead, I turned it on the Double Cluster in Perseus (also known as Caldwell 14 or NGC 869 and NGC 884).

In the 32mm eyepiece it was a nice rich star field, just the sort of thing I'd purchased the 905 for. Both clusters stood out very well against the very starry background and the line of starts that runs away from the area of the cluster stood out really well.

At around 21:43 UT I noticed that the sky was looking quite nice now. Still a little hazy but it looked quite impressive. The Milky Way stood out really well — I think this is probably the best I've seen it for most of this year.

Given that I couldn't get the 905 trained on M31 I decided to have a quick look with the 10x50 binoculars instead. Even though I was only holding them with my hands it was a very impressive sight. The more I looked the wider it appeared to get. I think this was probably the best view I've had of that galaxy since I started observing again.

While I had the 10x50s to hand I next had a look at M45. It looked very clear, very bright and the "mini cascade" in it stood out really well. I think this was probably the best view I've had for a long time.

At around 21:55 UT, while sweeping around Cassiopeia with the 10x50s, I saw a pretty obvious cluster of stars about way between Epsilon Cassiopeiae and Delta Cassiopeiae. Checking with my maps it turned out to be NGC 654 (also known as Caldwell 10). Checking back I have observed this before. It looked like a slightly fuzzy but loose collection of stars. Last time I observed I remember thinking that it looked more like a globular cluster but this time around it was obvious that it was an open cluster.

Starting around 22:05 UT I did a bit of aimless sweeping around with the binoculars, just taking in the beauty of the sky. However, it was starting to get colder and damper (dew was forming on everything) and given that I wasn't really dressed for the conditions (I had, after all, intended to just pop out for a quick look for Uranus) and that I really needed to get off to bed I decided to call an end to the session at 22:15 UT.

Notes:

Despite the weather being less than ideal I decided to use a break in the clouds to give my newly acquired Antares 905 a quick test. Conditions were quite misty with a warm dew forming on most surfaces.

Quick Test of the Antares 905

From: 2006-03-24 20:24 UT
To: 2006-03-24 20:44 UT

Quickly set up the 905 and roughly polar aligned the mount. Dropped in my new 32mm eyepiece and swung the 'scope around to M45. Despite not using the red-dot finder I'd ordered with the 'scope (it needed aligning and I suspected that I wouldn't have enough time to do that and to observe something too) I managed to get the cluster in the field of view with very little effort.

My initial impression was that the image was crisp and bright. There was no obvious false colour anywhere in the field. I then switch to the 25mm eyepiece and found that the quality of the image was just as good.

I then decided to try what might have been an unfair test: I pointed the 905 at Saturn. After finding it (with very little effort) in the 25mm eyepiece I switched to the 6mm eyepiece. I was delighted to note that the image appeared crisp and sharp, still with no obvious false colour.

Despite the conditions being less than ideal, and despite the fact that the 'scope had been given no cool-down time at all, I'd happily say that the view I had of Saturn was the 2nd or 3rd best view I've had since I got back into observing a year ago. The Cassini Division kept popping in and out of view, as did a hint of banding on the planet. If Saturn looks like this in the 905 in less-than-ideal conditions I'd be interested to see what it would look like in ideal conditions.

At this point I decided to give the 6mm eyepiece a go along with the 2x barlow but at that moment cloud rolled in and obscured Saturn (and, quickly, the rest of the sky). Given that rain had been forecast I decided to quickly pack up and call it a night.

International Space Station

From: 2006-01-11 16:51 UT
To: 2006-01-11 16:57 UT

The sky was still light, although the Sun had set. I managed to pick out the ISS when it was something like 20 above the horizon (perhaps a little more). At its maximum altitude (around 69) it was very bright, brighter than I've ever seen it before. I also watched it pass about way between Mars and M45.

Notes:

First clear night this year and the first clear night I've had free to observe in a month. The Moon was quite high in the sky, phase was waxing gibbous (about 89% of full). The main aim for this session was to observe Saturn (this would be the first telescope observation of the planet since 2005-05-07.

Saturn

From: 2006-01-11 21:22 UT
To: 2006-01-11 22:10 UT

Got Saturn in the field of view of the 130M, using the 25mm eyepiece with no trouble. Even at such low power the rings were quite obvious. I could also easily see Titan and Rhea. The image was a little unsteady (with some blurring and false colour) but, at this point, the 'scope hadn't really had much time to cool down so I wasn't expecting too much.

Switched to the 6mm. The image wasn't very sharp and was mostly unsteady. However, in steady moments, I was sure I was getting a hint of the Cassini Division.

Decided to play with some of the filters and see what effect they had. Started with the #15 Yellow/Orange filter. With it I thought I could see a good hint of a couple of dark bands on the surface of the planet.

I next tried the #21 Orange and then the #56 Green filters. In both cases I didn't notice any obvious improvement over the view without any sort of filter.

Finally I tried the #80A Medium Blue filter. When using this I'm sure I got a better hint of the Cassini Division than I'd had with any other view.

As a quick test I tried the 6mm eyepiece with the 2x barlow. The view was terrible. This was to be expected as this provides slightly more magnification than the 130M can handle.

I next tried a view with the 10mm eyepiece and the 2x barlow. The view was reasonably good but didn't really seem to show any more detail than any other view I'd had.

A good view of the Cassini Division still eludes me.

Saturn and The Beehive

From: 2006-01-11 22:28 UT

Temperature: 1.6C ...
Dew Point: -0.4C ...
Humidity: 87% ...
Wind Speed: 3.5mph ...
Wind Dir: West South West ...

Used the Meade 10x50 binocular to view Saturn and M44 in the same field of view. Looked fantastic! Having spent the best part of the previous hour observing Saturn through the 130M (where the planet was a significant feature in the field of view), this view, with M44 in the field, seemed to make Saturn look very small.

Also noticed that Asellus Australis was nicely framed in the field too. All in all an excellent sight and right in the middle of Cancer.

Moon and Elnath

Time: 2006-01-11 22:36 UT

While looking at the Moon with the naked eye I noticed a bright star close by (about 1 or so away). Against the Moon's brightness it was hard to make out but it was simple to see with the binocular. A quick checked showed that the star in question was Elnath in Taurus

One last view of Saturn

From: 2006-01-11 22:54 UT
To: 2006-01-11 23:00 UT

Decided to have one last look at Saturn before packing up. Used the 6mm eyepiece on the 130M. Had some very steady moments in which I thought I could see a very good hint of the Cassini Division. Also, in this view, the rings stood out really well against the planet.

Also experienced a couple of moments of really bad seeing. This little observation was a really nice example of the "watch and wait" approach to viewing planets. One moment the view was awful, the next it was the best I'd seen it all evening.


2005-11-09


Location: Billingborough (South Lincolnshire, UK)
From: 2005-11-09 21:30 UT
To: 2005-11-09 23:30 UT
Equipment: Naked Eye
Meade 10x50 Binoculars
Temperature: 4.0C
Humidity: 75%
Notes:

Reasonably clear night, some haze obvious closer to the Moon (which was just past first ). Felt rather cold. Decided to have a session out with chair and binocular, mostly with a view to having a good look at the Moon and also hunt down the clusters in Auriga.

The Moon

From: 2005-11-09 21:35 UT
To: 2005-11-09 22:11 UT

Started out by having a look at the Moon with the binocular mounted on a tripod. Lots of very obvious features were visible on or close to the terminator.

Noted that the terminator was running more or less through the middle of Mare Imbrium and that the shadows of Montes Apenninus looked long and very obvious. Also noticed that Archimedes, Aristillus and Autolycus were standing out really well too. The terminator also seemed to be running pretty much through the middle of Plato.

Towards the Moon's North Pole I could see what appeared to be a rather deep looking crater, in the terminator, with the back wall (this being in relation to the direction of the Sun) brightly lit but with the floor in shadow. Looking at my Lunar map I got the impression that I was looking at Anaxagoras.

Noticed quite a striking ray running diagonally — from "top right" to "bottom left" — through Mare Serenitatis. I could see that it seemed to be heading away from (or towards) a crater which, after looking at my map, appeared to be Atlas.

By 22:11 UT the Moon was heading out of sight behind some trees and it was also being lost behind haze towards the horizon.

M42

From: 2005-11-09 22:16 UT
To: 2005-11-09 22:23 UT
Temperature: 3.7C
Humidity: 77%

By now Orion had mostly risen and it was possible to see M42. Decided to have a look with the binocular mounted on the tripod. At first glance it simply looked like a sparse grouping of stars but, with averted vision, there was a definite hint of nebula. It might just have been my imagination but there did seem to be a hint of the "fan" shape that is so well known from drawings and photographs.

Clusters in Auriga

From: 2005-11-09 22:27 UT
To: 2005-11-09 22:37 UT
Temperature: 3.6C
Humidity: 77%

Swept Auriga for M36, M37 and M38. Found them all with no problems. Each one of them was a very obvious hazy patch — they all look like good targets for the telescope.

Given their appearance in the binocular, if I hadn't known they were all open clusters, I'd have assumed that they were actually globular clusters.

M35

From: 2005-11-09 22:38 UT
To: 2005-11-09 22:47 UT
Temperature: 3.4C
Humidity: 77%

While sweeping around the area near Auriga with the binocular I stumbled upon M35, another open cluster — this time in Gemini. This one looked very much like an open cluster. Again, this looks like it might make for an interesting telescope target.

M45

From: 2005-11-09 22:49 UT
To: 2005-11-09 22:56 UT
Temperature: 3.3C
Humidity: 77%

Given that they were now quite high in the sky I decided to have another look at M45 (AKA The Pleiades). They were too high up to comfortably view them with the binocular on the tripod (it's only a medium-height tripod) so I decided to try my monopod instead (it's actually taller than me when fully extended). This actually worked rather well.

The field looked very rich with stars, some seeming to pop in and out of view as I moved my eyes around. I also noticed something that I don't think I've noticed before: a striking line of stars that have a sort of "dog leg" look to them. For some reason they sort of reminded me of a small, bent version of Kemble's Cascade.

Mars

Time: 2005-11-09 22:59 UT

While taking a little break from the binocular I say and just looked at Mars with the naked eye. I realised that this must be the highest and brightest I've seen it in the sky for this apparition. I was tempted to go and get the telescope out to have a look but by the time it would have cooled down enough I'd probably be ready to call it a night. Also, the air wasn't terribly steady anyway so I wouldn't have expected a good view.

NGC 1528

From: 2005-11-09 23:11 UT
To: 2005-11-09 23:24 UT
Temperature: 3.6C
Humidity: 78%

Started sweeping around Perseus and stumbled on what seemed to be a small, tight, hazy cluster. It seemed similar in appearance to the views I'd had of M36, M37 and M38 earlier on in the session. I checked on my Messier and Caldwell charts and couldn't see anything close to the location of the object. I next checked with a more detailed chart and noted that there were a number of NGC objects in the general location. NGC 1444 seemed like the most likely candidate based on location alone.

Knowing that I'd need to do some checking later on I noted that the object was about two binocular field widths away from the "middle" of Perseus (taking the middle to be the area around Mirfak) and at a angle of around 8 o'clock if the general direction of the Double Cluster in Perseus is taken to be 12 o'clock.

Later on, I did some searching on the internet and found a couple of observation reports of NGC 1528, through binoculars, which seemed to have descriptions which matched what I'd seen. I did, however, also find a binocular observation report which suggested that NGC 1545 was a reasonable candidate too. Further checking with Starry Night, and looking at DSS images of the two clusters, suggested that NGC 1528 is the best fit for what I saw — both in its look and also in the look of the field of stars around it.

End of session

Cloud was starting to roll in so I decided to call an end to the session.


2005-10-04


Location: Billingborough (South Lincolnshire, UK)
From: 2005-10-04 19:26 UT
To: 2005-10-04 21:15 UT
Equipment: Naked Eye
Meade 10x50 Binoculars
Tento 10x50 Binoculars
Notes:

A rather cold and damp night. Some mist about, especially obvious towards the horizon. Most of the sky doesn't look all that dark although, above me, I can see the Milky Way with little trouble.

Decided to have a simple evening of binoculars and chair, just sweeping about to see what I can find. No real point or target for the session.

Kemble's Cascade

Time: 2005-10-04 19:50 UT

At around 19:50 UT I stumbled upon Kemble's Cascade in Camelopardalis. Fantastic little asterism.

Although I've read about it a number of times before this was the first time I'd seen it for myself and I was quite surprised at just how straight the line of stars appeared to be. I was very happy to have finally seen it.

At 19:58 UT, while looking with the binocular, I saw a very faint satellite pass right through the cascade, about two thirds of the way "down" the line.

Mars and M45

Time: 2005-10-04 20:17 UT

Noticed that Mars and M45 had now risen above the roofs to the east of me. Looking at them both with the binocular I estimated that they were no more (and perhaps slightly less) than two binocular field widths apart.

Mars, in the binocular, was interesting in that it was obviously a non-stellar object. I'm not sure if this was just down to brightness/contrast or if I actually was seeing a hint of a disc. The colour in the binocular was a rather vivid orange.

By 20:27 UT there seemed to be more mist forming. It was getting increasingly hard to see M45 with the naked eye. The sky above me, however, seemed as clear as ever — perhaps a little darker and clearer than it was at the start of the session.

Mist and smoke

Time: 2005-10-04 20:27 UT

By 20:27 UT there seemed to be more mist forming. It was getting increasingly hard to see M45 with the naked eye. The sky above me, however, seemed as clear as ever — perhaps a little darker and clearer than it was at the start of the session.

Also, around this time, I noticed my first hazard of winter observing: smoke from people's fires. Given that nights are getting colder now and given that I'm surrounded on three sides by people who have and use open fireplaces I wonder how much of an obstacle this will be?

NGC 1502 and testing dark adaption

Time: 2005-10-04 20:56 UT

After checking a couple of books, a couple of charts, and some pages on the net I realised that, earlier, when I'd been looking at Kemble's Cascade, I'd also been looking at NGC 1502.

At this point I realised that the cascade is also an interesting test of how dark adapted I am. I'd popped indoors to check the books, charts and the net and, obviously, I'd exposed myself to normal lighting and so had ruined the dark adaption that I'd built up earlier. When I came back outside and went to look at the cascade again I could hardly make it out — initially all I could see were the brighter stars that are around it.

As the minutes passed the cascade again became more and more visible in the binocular. I think this might serve as a useful gauge of how dark adapted I am (and how transparent my skies are) during the course of winter.

The Hyades

From: 2005-10-04 21:11 UT
To: 2005-10-04 21:15 UT

At 21:11 UT I noticed that the Hyades (AKA Melotte 25, Caldwell 41) had cleared the roofs to the East of me. While they were hard to make out with the naked eye due to the rising mist I could clearly see them with the binocular.

In the binocular Aldebaran was interesting to watch as it was twinkling between red and green. I took from this that the mist really was making a mess of things and that the air wasn't very steady at all. Earlier I had been thinking about getting the 130M out to have a look at Mars but at the time the rising mist put me off. If the view I had of Aldebaran in the binocular was anything to go by this was probably a good decision.

By 21:15 UT the cold and the damp was starting to get a little too much so I decided to call an end to the session. I wasn't really that well dressed for the conditions — I'm going to have to dig out some of my winter gear for future sessions.

Location: Billingborough (South Lincolnshire, UK)
From: 2005-09-13 10:20 UT
To: 2005-09-13 10:31 UT
Equipment: Solarscope
Naked Eye
Notes:

Another look at sunspot 798 with the naked eye and with the Solarscope. Sky wasn't too bad again today — just a little hazy.

Sunspot 798

From: 2005-09-13 10:20 UT
To: 2005-09-13 10:31 UT

First looked for sunspot 798 with naked eye and eclipse shades. It was very easy to see as a rather large dark spot.

In the Solarscope it was obvious that the shape of the spot had changed a lot from yesterday. Although the following sketch gives the impression that it's smaller than yesterday it actually seemed to cover slightly more area than I remember from the previous observation.

Made the following sketch:

Sketch of Sunspot 798

Location: Billingborough (South Lincolnshire, UK)
From: 2005-09-13 21:55 UT
To: 2005-09-13 23:00 UT
Equipment: Sky-Watcher Explorer 130M
Notes:

Given that the sky was reasonably clear and that the forecast for the next few days didn't look too good I decided to have a quick session looking at Mars.

Conditions were slightly warm and breezy with the Moon just past 1st .

Mars

From: 2005-09-13 21:55 UT
To: 2005-09-13 22:49 UT

Mars was still quite low. There was also a hint of haze in the air which seemed to dim it slightly. After first locating the planet with the 25mm eyepiece I switched to the 10mm eyepiece. The image was quite washed out and was dancing around quite a bit. Initially about all I could make out was that there was a visible phase.

The breeze calmed down for a moment so I switched to the 10mm with 2x Barlow. As normal I struggled to get useful focus with the Barlow and also noticed that there was some significant false colour around the image of Mars.

Switched to the 6mm (with no Barlow) and the image was much crisper. Mars appeared very bright, even to the point that I was getting four very obvious spikes off it. In steady moments there was a hint of surface markings visible. As with a few nights ago, these appeared as vague differences in colour.

Added the #21 Orange filter to the 6mm eyepiece. This reduced the glare of the image, the surface looking less washed-out. The hint of markings seemed to improve although they didn't improve to the point that I'd have been able to draw a reliable sketch. They were there, visible but also somewhat indistinct. The fact that the image wasn't terribly steady most of the time adding to the problems.

Next gave the #80A Medium Blue filter a go with the 6mm eyepiece. I don't know why but I was initially surprised to see that this made Mars look white, not blue. The markings mentioned above were still visible and, this time, appeared as darker gray areas.

Decided to experiment a little more by combining the #21 and #80A filters. The image looked more or less the same as it does with the #21 filter on its own although I'd be tempted to say that the darker areas appeared a little easier to notice — although still somewhat indistinct.

Also tried the #56 Green filter with the 6mm eyepiece. Other than making Mars look somewhat green this didn't seem to make an awful lot of difference to the image.

M45

From: 2005-09-13 22:57 UT
To: 2005-09-13 23:00 UT

Because it was close to Mars and is also an easy target I decided to have a quick look at M45 — The Pleiades. Had a look with the 25mm eyepiece. Quite a stunning sight through the 'scope. The main pattern of stars more or less filled the field of view.

By around 23:00 UT the breeze was picking up quite a bit and the sky was becoming more washed-out due to the Moon so decided to call an end to the session.
