Apologies if this has been covered.


If I have a large number of subs, hundreds or thousands (some nights are 600 subs-all from same camera/optics), putting processing time/computer concerns aside, is there any difference in the outcome if I do all at once or do multiple groups and then stack the groups? 


DSLR or 16mb 4/3rds mono camera if that makes a difference.

Not really no, it's even adviced to stack in groups then and combine those integrations later. I would not go under 30-40 frames per integration though, so the outlier rejection algorithms work nicely.
