Description

I shot M51 using Gain 139 and Offset 21, which is Unity Gain for my camera, to get a bit more dynamic range than when I shoot at a higher gain setting. The core of M51 is not as overexposed at when I shoot at higher gain. Also, I'm learning how to take and use flats, so this image has a master flat applied.
