I think Rod & Matt have made an excellent point. I use my XW 7 all the time for all kinds of viewing, but my focal length is a mere 1.6 metres, so it is generates 230x in my scope. That's as high as I want to go on average nights. An XW 10 in your C8 would produce 200x (corrected); again, probably about as high as you want to go on most nights.

Barry Gooley is the manager & he is great to deal with.
Oh, I think John posted at the same time I did. I agree with all his comments - except, I think it will outperform the Meade by 12 light-years.
