The D5300 and QHY294C are 14 bit cameras. The Ha modification did improve the camera’s sensitivity and I noticed more detail in faint galaxies. I decided to start putting together some comparison images. The images presented here used master DARKs, FLATs and BIAS. The Bubble Nebula was my first comparison. This is a cropped…
