RGB combine question

Posted By dietmar hager
hi Luca,

neither sum nor average.
best methode is to sigma clip the single frames, as this will deal with lots of artefacts like hot pixles and noise.
the downside - this methode requires quite a long tota lexposure time.
in case you do not have much exposure time, average would be better.
simple sum augments all kinds of artecats and you run rhe risk of "overexposing" bright parts...
hope this helps...?
