Image Details:

This was my first attempt to image a more faint deep sky object (magnitude 9, I believe) without any location assistance. It took me quite a few iterations to get the object in the frame. Nova's online astrometry tool assisted me in my test shots.

Went a bit aggressive on my ISO at 6400 with my Canon T3 (unmodified) fitted with an SVBONY CLS light pollution filter. Took 48 1 minute subs followed by 24 each of all calibration frames.
