mariusvr Wow your picture looks very contrast !! )
As for me I process the whole picture , I don't know how to process it separately unfortunately(( If you can point me will be really appreciate
gmadkat Im gathering the data every night when the weather is allowed now. Its really clear for last week so I have a lot already))). But can you explain pls the proper way to merge it together?For example a have a light+flat+bias frames from day 1, 2 and 3 , flats and bias are different for every day , light also can have different angle, exposure time, sensor temp etc. Should I merge everything all L + all F +all B +all D оr I need to stack it separately by day and then somehow merge staked images for every day? The same question for stacking L with O+H filter frames.
