Description

This is the first DSO I could collect some significant subframes on with my new ASI183MC pro dedicated camera. I didn't take any calibration flat frames and instead used software flat correction techniques to get around the radial gradient that most refractive optics suffer from. For galaxies that are round and have a well-defined structure, it's not too tricky to use the "dust and scratches" flat correction technique that Trevor Jones from AstroBackyard demonstrated many years ago.  Considering I live in a Bortle 7 light pollution zone, I feel the level of detail I was able to achieve with just 6 hours of integration time isn't too bad.
