     This is not a universally held opinion.  The "typical" deep-sky
object (beyond the showpieces) are about twice the size of Jupiter,
so obviously you end up using fairly high power, equivalent to a
1.5 to 1mm exit pupil on whatever telescope is in use (smaller for
small telescopes, larger (maybe 2mm) for larger telescopes).
