I want to make sure I don't waste my money on an eye piece I may or may not use. Can anyone suggest which would be the most practical one to get. My scope is a SE8 and I want to get good magnification from the stars and moon. I have a plossl 25mm one on my scope already and a 6mm one in my cart on a site but have not yet paid for it so can change it if needed.

A few have told me a 6 or 10 would be good but want to be sure.
