QHY183C M83 imaging session
The image above was the result of 30 x 100 second frames taken with a QHY183C one-shot-colour CMOS camera fitted to an AP130GTX and QUAD compressor. Guiding was with a SBIG STi Guider kit. Autocapture with MAxImCCD, which also ditherd the sub exposures over a 2.5 pixel range. Some high Cirrus cloud drifted though during some sub-exposures, which gave brighter stars an eye-pleasing halo, hence were not removed from the data stack.
