NGC 3169, NGC 3166, NGC 3165, and NGC 3156 are all cosmic neighbors approximately 75 million light-years away in the constellation of Sextans. The two largest members, NGC 3169 (left center) and NGC 3166 (right center), are interacting and they are estimated to be only 160,000 light-years apart. NGC 3165 is the small galaxy oriented vertically just to the right of NGC 3166 and NGC 3156 is a lenticular galaxy shown on the lower right. I did pull some detail but not as much as I would have liked as all of these galaxies are on the smaller size for my setup. NGC 3169 is an asymmetric unbarred spiral galaxy with a very noticeable dust lane as seen even on my image and home to a couple of supernova events in the last 50 years.
I did crop it quite a bit but there is only so much you can do, that is why they invented bigger telescopes. Fortunately the wide field has a lot to offer such as other galaxies scattered throughout and also a colorful starfield. I have been processing nebulae for months now and this was a delightful change.
