Hi all,
Started collecting data for a second object this year - NGC 4945.
I am not accustomed to producing RGB images so it will be an interesting experience.
So far have only a few hours of Lum with my 4" refractor. Experimenting with not using any calibration files (no bias, no darks and no flats) and no noise reduction at all.
