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.

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.
