60 lights, 30 darks, 100 flats, 100 bias.
Altair Astro 66ED refractor, Altair 183C V2 camera, AVX mount, Planostar 0.8x flattener/reducer.
Capture software SharpCap v3.2 beta.
Focus with Bahtinov Mask, unguided.
Bias frame checked with FITS Liberator to ensure balanced histogram, used to decide black level setting.
Stack produced using Siril plus colour calibration, SCNR & colour saturation. Stack finalised with GIMP 2.10. About 1 hour for calibration and processing.
Looking at the histogram, I will reprocess the stack as some work needed on colour balancing.
