That strategy is probably fine. I am not sure just what the sky monitor
threshold is set to, but I expect it is some sensible value.  We can
certainly tolerate some moon, but the actual brightness is a complicated
function of the moon phase and position and the position being imaged.
Rather than devising some complicated ruleset, it seemed easiest to just
say don't image with the moon up.  For those times when you are in the
middle of a scan, utilizing the sky monitor to determine how long to go is
sensible.
