DSOs Messier 51 - Whirlpool

70x 300s R, 55x 300s G, 55x 300s B, 45x 300s Lum, Darks, Flata, Bias.

Kinda disappointed with how this came out. I feel like with this much integration time I should be getting better detail. I have more experience with nebulae so my galaxy processing needs some work. I will probably push the luminance quite a bit further before adding in any H-alpha.

Stacked and processed in pixinisght with RC Astro plug ins

Equipment: WO ultracat 108mm refractor, ASI 2600 MM camera, HM17 mount, Askar 52mm guide scope, ASI 120 mini guide camera, ZWO Automatic Focuser, Optolong LRGB filters, ZWO filter wheel
