Saw earlier on in the day that the ISS would be making a good pass this evening so I decided to have a go at photographing it.

Leo, Saturn and the ISS

From: 2007-04-18 20:15 UT
To: 2007-04-18 20:40 UT

I went outside at around 20:15 UT and set the Canon EOS 400D on a tripod. I decided that the best place to photograph would be Leo. I took a couple of test shots and had a bit of trouble sorting out the focus but I more or less got it right in the end.

At around 20:30 UT (I wasn't making notes of exact times as I was too busy working with the camera) I saw the International Space Station slowly heading in from the west. A short while later, as it got close to Leo, I started the exposure. Annoyingly it's just a 30 second exposure because I'd forgot to put the camera on bulb (while I would have had time to do this I've also not used bulb mode with remote I use and wasn't sure how it works, rather than miss the pass I decided to go with 30 seconds).

As it was, despite the odd problem or two, the image seemed to turn out okay, it shows Leo, Saturn and the ISS:

2006-05-01


Location: Billingborough (South Lincolnshire, UK)
From: 2006-05-01 20:10 UT
To: 2006-05-01 22:17 UT
Equipment: Naked Eye
Meade 10x50 Binoculars
Antares 905
Sky-Watcher Explorer 130M
Temperature: 8.9C ...
Dew Point: 2.8C ...
Humidity: 66% ...
Wind Speed: Calm ...
Pressure: 1003.3hPa ...
Notes:

Calm, clear evening. Still light when I first stepped out. Some high-level haze was visible but it seemed to be patchy and didn't look like it would cause much of a problem. Waxing crescent Moon (about 12% illuminated) in the western sky.

The main plan for the evening was to try and observe comet 73P-C Schwassmann-Wachmann 3. With this in mind I set up both the 905 and the 130M — the idea being that the former would be useful for locating the comet and the latter would be better for actual observing once I'd located it.

The Moon

From: 2006-05-01 20:14 UT
To: 2006-05-01 20:30 UT

While waiting for it to get dark (and while letting the 130M have plenty of time to cool down) I decided to turn the 905 on the Moon. I started with the 25mm eyepiece. Right away the earthshine looked very impressive, good enough to see plenty of features on the night side of the Moon.

Mare Crisium was fully illuminated with the terminator running through Mare Fecunditatis.

I spent a little time using different eyepieces and quickly running up and down the terminator, enjoying the sights of the various craters and mountains that could be picked out. I made no serious effort to do any real lunar observing as that wasn't the main point of the evening.

I then spent a bit of time trying to get a couple of images, through the 25mm eyepiece, using the camera in my mobile phone. Sadly the day-side of the Moon was always too washed out and none of the images were any good.

Saturn

From: 2006-05-01 20:37 UT
To: 2006-05-01 21:00 UT

Next, while waiting for it to get dark enough to look for the comet, I decided to have a look at Saturn. I started with the 905 and the 10mm eyepiece. Right off the planet's shadow on the rings was obvious. The image was sharp but often unsteady. There was no obvious hint of the Cassini Division.

Next I switched to the 6mm eyepiece and there was a good view of the shadow of the rings on the planet. There was also a faint suggestion of banding on the planet's surface. The image wasn't as steady as previous sessions but, with the 6mm, I did start to get the odd hint of the Cassini Division in steady moments.

One thing that was very obvious was, when compared to the last couple of views I've had of Saturn with the 905 (2006-03-24 and 2006-04-03), the planet was looking smaller than I recalled.

Next, as a comparison test, I turned the 130M on Saturn. Using the 6mm eyepiece the image was (obviously) much bigger than with the 905 but it was also much softer too. At no point could I get as sharp a focused image as I could with the 905. I'd say that the 130M didn't give me any more detail on Saturn than the 905 did, perhaps even a little less. The image was, obviously, much brighter with the 130M.

I find it hard to believe that there'd be that much difference between the two, this suggests to me that I really need to give the 130M a good check-up and redo the collimation (it has been a long time since I checked the collimation).

International Space Station

Time: 2006-05-01 21:08 UT

Noticed a very bright satellite heading west to east, just below Leo. Watched it head down into Virgo and then fade. Given the look, location and speed I suspected that it was the International Space Station.

Checking later, it was the ISS.

Haze starting to form

Time: 2006-05-01 21:12 UT

Noticed that some thicker high-level haze was starting to form. This was causing a slight halo around the Moon and, looking over to Hercules, I could see that it was difficult (but not impossible) to see the Keystone asterism.

Satellite

Time: 2006-05-01 21:18 UT

Watched a satellite pass south to north just west of Botes.

According to `stella' on the SPA BB what I saw was a rocket body called Resurs 1-4.

First look for Comet 73/P-C Schwassmann-Wachmann 3

Time: 2006-05-01 21:27 UT

Despite the fact that conditions were less than ideal I decided to have a first go at looking for Schwassmann-Wachmann 3. Using the 905 with the 25mm eyepiece I started out at Epsilon Herculis and worked my way to the general location of the comet (actually, fragment C of the comet — that's all I was concentrating on this evening — mostly because I ran out of time and good conditions). With no effort at all I found the comet.

The general impression was that it was faint, fuzzy and conical shaped. With direct vision it was almost impossible to see but with averted vision it was easy enough to detect. At times there was a hint of blue/white colour to it.

Next I dropped the 32mm eyepiece in the 130M and located the comet with that. This time I could see it with direct vision and there was a very obvious hint of a tail — even more so when averted vision was used.

Still on the 130M I then switched to the 25mm eyepiece and then the 15 mm eyepiece but found that, the shorter the focal length I used, the worse the image became. The 32mm eyepiece was easily giving the best view.

At this point, using the 130M and the 25mm eyepiece, I made a mental note of the location of the comet in relation to the stars close by with a view to seeing if I could detect movement with a later observation.

Comet 73/P-C Schwassmann-Wachmann 3 with 10x50 binocular

Time: 2006-05-01 21:45 UT

I grabbed my Meade 10x50 binocular and quickly located the comet without any effort. It was very obvious — impossible to miss. When compared with M13 the comet appeared bigger and more diffuse.

Jupiter with the naked eye

Time: 2006-05-01 21:55 UT

From the bottom of the garden I noticed, through some trees over the road from me, that Jupiter was up and looking very bright. Sadly, given the position, it was almost impossible to use either of the telescopes to have a look. Given that Jupiter is going to be rather low to the horizon for this apparition there's a good chance that I won't get to observe it (at least not from home) as it'll probably be obscured by the house most of the time.

Second look at Comet 73/P-C Schwassmann-Wachmann 3

From: 2006-05-01 22:10 UT
To: 2006-05-01 22:17 UT

After a short break I went back to the 130M with the 25mm eyepiece to see if I could detect any movement (based on the earlier mental note). It was instantly obvious that there had been movement in that time. Given the rate of movement I saw in such a short period of time I noted that it would be interesting to see how the location compared on subsequent nights (assuming, of course, that the weather plays ball and I get the chance to observe it again any time soon).

By 22:17 UT thicker haze had moved in from the west and it looked like it was more or less horizon to horizon. At this point I decided to call an end to the session.

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
To: 2006-01-11 22:35 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.


2005-05-04


Location: Billingborough (South Lincolnshire, UK)
From: 2005-05-04 20:50 UT
To: 2005-05-04 21:50 UT (approximate)
Equipment: Sky-Watcher Explorer 130M
Meade 10x50 Binoculars
Notes:

Seeing seemed reasonable tonight. No moon.

Didn't get a chance to look at Jupiter as it was obscured by the house early on and by the time it cleared the house cloud had started to roll in from the south.

Saturn

Time: 2005-05-04 20:50 UT

With the 10mm eyepiece on the 130M I thought I could see the faint hint of a band on the planet's disk. Not really sure if this really was there or if my eye/mind was playing tricks on me.

As with previous sessions I kept getting the odd hint of the Cassini Division.

At just before 21:00 UT, while looking at Saturn with the 10mm eyepiece and 2x Barlow, had a meteor pass right through the field!

Titan was obvious and, with the 10mm and 2x Barlow, I noticed another faint point quite close to the planet (I'd estimate a couple of Saturn diameters away in the field). Wasn't sure if I was seeing another moon or perhaps a background star. Checked the following day with Starry Night and it seems that what I was seeing was Saturn's moon Rhea.

The International Space Station

Time: 2005-05-04 21:15 UT (approximate)

Naked eye this time (obviously). While having a break from the telescope for a moment saw a very bright satellite moving West to East, easily as bright as Jupiter. Saw it pass within two or three degrees of Jupiter. As it headed East it dimmed and disappeared from view as it past into Earth's shadow. Suspected at the time that what I'd seen was the ISS.

Checked the following day with Starry Night: yes, it was the ISS .

M44

Time: 2005-05-04 21:30 UT onwards

Had another look at M44 with the binoculars and then turned the 130M on it using 25mm eyepiece. Very impressive. More stars that I'd care to count.

Noticed with the binoculars, reasonably close to M44, there's an asterism of stars in a roughly straight line. Got to wondering if it's got a name.

Did some checking on the web the following day and couldn't find any mention of it. I guess it's not an asterism of note. Checking in Starry Night it seems what I was looking at is comprised of the following stars (plus some others):

If anyone reading this recognises this asterism and knows a name for it I'd love to hear about it.
