Description

After imaging a few DSOs with a DSLR or using EAA, this is my first attempt with a dedicated CMOS camera using 16-bit RAW color space saved as FITS. TIF and PNG formats are saved in monochrome and may need to be "bayered" back. Still need to figure this in detail. After a first employment I am now an advocate of Bahtinov masks. The soft tone and large bright stars with halos are the result of haze somewhere high up in the air and due to the fact that I used an LPR only without an UV/IR cut filter. Anyway, the softness exhibits its own charm and helps hide background noise. Unscheduled diplomacy!
