Description

Large edge-on spiral galaxy, with lots of star forming activity. Prominent dust lane bisecting the plane of the galaxy, with numerous smaller "chimneys" of dust and gas. This relatively bright galaxy is a popular and rewarding target for astrophotography. Beautiful object. I wonder what it would look like face-on.

Monochrome camera and L,R,G,B filters. Captured images over two nights, one night of R,G,B images and one night of L images.

The acquisition details above include all exposures. The final image used
L - 54 frames (of 75) x 300s @ Gain 200 @ -10C = 4h 30m exposure time
RGB - 28 frames (of 28) x 300s @ Gain 200 @ -10C = 2h 20m exposure time, each
11h 30m total exposure time

No color enhancement beyond the calibration and white balance.
