CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!
Will try to look for the reference source also later in the day. Gotta go for a meeting now.

Basically, 'Add' will increase the SNR for faint images, but also increases the noise (although not to the same extent).
For images that are adequately exposed, 'Average' or 'Median' will reduce the background S.D. (noise).
My favourite is 'Median', YMMV.
