Cluster NGC 663 and NGC 654

Posted By Jim Thommes
Here is a double cluster shot of NGC663 and the smaller NGC 654. Full size image and exposure / processing details are at:

Apologies for the orientation (North to the left) - I liked the presentation in that orientation. You will have to orient the image 90 Deg, CW mentally to compare to other images.

Sharpless 235

Posted By Jim Thommes
Here is one of the Sharpless objects, SH2-235. It ended up a bit noisy and some reflections with bright stars, but it was a fun catch and process. Full size image and exposure / processing details are at:

M34 and some faint fuzzies

Posted By Jim Thommes
Back in November, I had turned my attention to M34. Here is the full size image and exposure / processing details:

http://jthommes.com/Astro/M34.htm
(be sure to click on the image for a full size view)

If you crank up the gamma on your monitor in the full size view, (besides seeing noise and all my data / processing flaws) you can see some small faint galaxies in the 15 - 17 Magnitude range hiding in the noise and jpeg artifacts. There are 2 in the upper right, 3 in the lower right, 2 in the lower center, 6 in the lower left and 1 on the left edge. These were identified from the PGC. Looking at the Digitized Sky Survey, I think there are more.

Lower's Nebula

Posted By Jim Thommes
Here is an image of Sharpless 261, a.k.a. LBN 864, a.k.a. Lower's Nebula. I wish I could have done a bit better with the framing.

M35 / NGC 2158

Posted By Jim Thommes
I guess this is a pretty notable pair of open clusters. M35 is a close, intermediate age cluster while NGC 2158 is an old and distant cluster. Full size image is here:

M77

Posted By Jim Thommes
Greetings All,

The new year has been very busy for me in areas not astronomical (work has been particularly demanding), so its been about two weeks since a post. I found some time for processing on M77 data. Image and exposure / processing details are at:

http://jthommes.com/Astro/M77.htm
(be sure to click on the image for full size)

There is a faint outer disk on M77 - I think I got just a hint of it.

NGC1097

Posted By Jim Thommes
Well this is a tough nut for me given my equipment. I have more noise than I would want and as close to the horizon as it is, I guess I should expect some difficulty. I have to say I was at a dark sight and I couldn't complain about the seeing. Anyway, I thought I would share the results:

Sharpless 297

Posted By Jim Thommes
This object is also known as LBN 1039 and Gum 3. It is located about 1.5 degrees south of the Seagull Nebula Gum 1 and about 6 degrees from Sirius. It was my last data set from 2007 (taken Dec 15). A full size image and exposure / processing details are at:

Open Cluster - NGC 2345

Posted By Jim Thommes
Here is a somewhat plain result from my first night out in 2008 (Jan 11). Its been a struggle with weather this year, but this is the first of a hopefully better rest of the year. NGC 2345 is small sparse open. It is moderately young but contains several red giants as well as some bright blue giants. Full size image and details are here:
