Description

M31 using a combination of OSC and Mono camera.

The RGB image was an integration of 6.5 hours of data from ASI2600MC, and the HA data was 11 hours of integration from ASI1600MM. Both were captured using Redcat51.

I live in a Bortle 8 zone. I dithered by about 10pixels. Still there was enough noise that MLT/MMT in linear state was introducing patchy artifacts. I used a very gentle amount of ACDNR in linear state. Later the image was star-reduced by Russel Croman's StarXTerminator tool (which I believe is superior than Starnet for most scenarios) and the noise was reduced.
