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.
