Well even 1 is acceptable. I usually aim for 10. But sometimes only have 3 (if it's 20 minute exposures and I am doing them manually that's a long time to sit around waiting for dark frames!), 5 is common, I have some groups with about 30.
10 is a nicenumber. 5 is defintely good. 3 or less is less than ideal.
