Stacking duplicated Images
Hi All,
I have often wondered instead of taking ( for example) 100 subs you take 10 clean dithered subs and then duplicate these 10 times and then stack? After all the reason for taking multiple subs is to reduce the SNR. Wouldn’t duplication of a few subs do the same?

Thanks

Chris
