M83
M83 Spiral Galaxy in Hydra.
Taken under a very bright moonlit sky. Short exposure total and the 600-second luminance sub-exposures have burned out the core so I'll add some shorter exposures when the Moon is less obtrusive.
Lum: 4 x 10m
Red: 3 x 10m
Green: 2 x 10m
Blue: 2 x 10m
67' x 67' FOV (cropped).
