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).

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.

Quickly dragged the Solarscope outside to do a sunspot count. The Sun was totally blank, not even a hint of the markings that I saw yesterday.

Cold, clear, but slightly hazy night. Decided to get the 130M out and have a look at M42 and Saturn.

M42 and M43

From: 2006-03-02 20:31 UT
To: 2006-03-02 21:05 UT

Set up the 130M with the 25mm eyepiece and pointed it at M42 and M43 in Orion. Despite having owned the 'scope for almost a year now this is the first time I've really had the chance to have a look at this famous object (mostly due to the nature of my horizon and how the weather has been for me).

Right off the classic "fan" shape was easily visible with an obvious separation between M42 and M43. Also, all four stars in the Trapezium were easily visible. There was no hint of colour other than a sort of silvery gray — no hint of the green that some people say they can see and I've seen myself in the past in a 10" Newtonian telescope (on a Dobsonian mount).

Switched to the 15mm eyepiece, this gave a view where the nebula was bigger than the field of view.

Using either eyepiece direct vision was all that was required to see the nebula, although averted vision suggested a greater extent and a little more detail.

I made the following very rough sketch as a reminder of what M42/M43 looked like in the 25mm (although I've drawn it a bit bigger than it appeared). Finished the sketch at 21:05 UT.

When I get the chance I aim to do a more complete sketch based on what I recorded in the above.

To: 2006-03-02 21:46 UT

Turned the 130M on Saturn. Found it with no problems using the 25mm eyepiece and then switched to the 6mm eyepiece.

Oh Wow! Every other time I've observed Saturn it's been a struggle to get a good view; it's always required patience and a lot of looking before any serious detail, especially the Cassini Division, has stood out. This view was totally different. From the very first moment the rings appeared nice and crisp, the planet's shadow on the rings stood out really well and the Cassini Division was immediately obvious.

I spent the next 20 minutes or so observing the planet and the quality of the image hardly ever changed. Without a doubt the best view I've ever had.

By 21:46 UT I was starting to get rather cold and dew/frost was starting to form on everything. With some reluctance I decided to pack up for the night.


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%

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.


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.


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.


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.


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

Time: 2005-11-09 23:30 UT
Temperature: 3.7C
Humidity: 78%

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