Andy's suggestion that you only go to about halfway on the 50x per inch rule is no doubt much closer to reality, and even then, in very still conditions only. If you are looking to invest in a good EP, you will use high power eyepieces the least, and midpower eyepieces the most. I expect something around the 10mm mark would be close to your sweet spot.

Thanks Rod you said it for me
I was just about to post something similar when I read your post.
I could never see a 5" scope using that sort of magnification
Cheers
