Description

The Leo Triplet (a.k.a. the M66 Group) is a small group of galaxies approximately 35 million light years away in the constellation of Leo. It consists of the three spiral galaxies M65, M66, and NGC 3628. From Earth NGC 3628 is on its side and resembles a hamburger and so it is also known as the Hamburger Galaxy. This galaxy group is very close to the M96 Group captured a couple of days prior.

I collected data over three nights, the first night being the best. I did a test on the data and decided to share it for anyone who is interested. As I mentioned the first night (3-22-17) the sky clarity was good. On day two (3-23-17) I had a mixture of decent sub-frames and some with a small amount of red tint and on day three (3-29-17) most of the sub-frames reddened and it was more severe.

I put example sub frames on my website at: http://kurt-zeppetello.blogspot.com/2017/04/the-leo-trio.html

The sky was not as good as I had though on the second or third nights so I had a decision that most of have to make, whether to use or not use this data. I checked the sub-frames carefully in Adobe bridge and deleted any frame with streaking or any other defect (except the red color). I did two versions with Deep Sky Stacker (DSS) and then processed them in the same way with PS, Astronomy Tools, and LR.
