This is M76 – the Little Dumbbell. It’s my third attempt at imaging with the ZWO ASI1600MM-Cool Mono camera. It still came out very grainy, no matter how much I lowered the gain and offset. But I did notice that I was not properly setting the cooling on the camera. If the camera is not cooled, it can produce a lot of noise. So that will be my next fix. I captured 10 raw images for the luminance filter, and 5 each for the red, green, and blue filters. Each exposure was 180 seconds. The total exposure time after stacking was just over 75 minutes. 10 dark, 10 bias, and 10 flat frames were also created (the flats were created for each filter). Here is more information below:
