Description

A large, almost edge-on barred spiral galaxy.

Captured images over two consecutive nights. Monochrome camera and LRGB filters (just acquired). Capturing went smoothly. Took 3 hours of L and one hour each of R,G,B each night. Not a super deep image, but came out nice.

The acquisition details above include all exposures captured. The final image used
L - 56 (of 72) frames x 300s @ Gain 100 @ -10C = 4h 40m exposure time
RGB - 24 frames (of 24) x 300s @ Gain 100 @ -10C = 2h 00m exposure time, each
10h 40m total exposure time.

During processing I had to crop a lot off of the top and bottom due to corrupted flats. Fortunately the galaxy itself was not affected.
