Some stars require coverage all night, if they are positioned well in
the sky. If your mount is not very good at multiple goto/unattended
operations...then stick with such stars. (That's what I currently do
most of the time.)
Some stars require brief coverage each night, but you can cover many
stars that way if your mount can slew and point well all night so that
you can sleep.
Some stars can be covered without any filter, allowing you to go
fainter. The CBA does this work 99% of the time.

CVNet also keeps track of fast acting stars:
