Hi All

I have a new SW Evostar 72ed and want to do some lunar viewing, what eyepieces would you suggest I look at?

Is there a general rule-of-thumb/formula for calculating aperture vs the diameter of the moon?

Should I look for a zoom eyepiece? Are these any good?

Also, as this is really not the main purpose of the scope, i would like to keep the costs at a reasonable level.

Regards
Chris
