Messier 27, The Dumbbell Nebula
I find Messier 27 to be one of the more intriguing planetary nebulae, with such interesting structure in each the hydrogen and oxygen. This is my second solid attempt imaging M27, made easier by my improved mount. I used a Celestron Edge HD 925 with a 0.7 reducer, an ASI 2600MC Pro, IDAS NBZ filter. I managed to get 6 hrs 40 minutes total exposure time, with 40 x 600s subs. I processed it in SiriL, Starnet and GIMP.
