NICE WIDE FIELD OF NGC 2158 WITH M35 IN THE FIELD.

It was and it was done in January of 2017. That was with my old G11 before I upgraded to the Titan base. G11T. I also have a bit of problems in the corners with the ES 127. It needs a good flattener.

Thanks

Aubrey

Aubrey: getting an error message when I try to follow the link in the email message but found it on the forum. Beautiful as usual! You do have a bit of vertical elongation in the stars making me think that your polar alignment may be a bit off.

Hi All, I am still catching up on processing. This image is from January 2017 that I shot from the Brickhouse Observatory on the Meyer Field. This is a combination of NGC 2158 Globular cluster (sometimes called the Spider)in the center with M35 Open Cluster surrounding parts of it(blue stars). They are located in the Gemini Constellation.

This is two hours exposure with the Luminance channel subs being 10 minute exposures. There is one galaxy in this wide field and it is PGC18441 at 18.55 magnitude. That makes this about 40,000,000 times dimmer than the Star Vega. If you look carefully on the left side of the Spider you can find a mark that I put to locate it. You might have to enlarge it quite a lot.

Hope you enjoy.
