I "personally" do not think it will be very beneficial...the internal baffle is only 1 inch wide in the C6... Only 1.5 inches in the C8 so even the C8 can not take full advantage of a 2 inch diagonal...BUT the gain with the C8 is worth the price

Bob, Do you mean the 2" diagonal is worth the money if you have the C8 or Get the C8 over the C6?

BIGGER IS BETTER! You get roughly 50% more light with the C8. So what's an inch and a half? It's 38mm. Even among 2" eyepiece there are not many that have a field stop larger than 38mm. If you have a collection of 2" EPs go for it, but I wouldn't start one for a C6.

Personally, I was shocked when I inventoried my EP collection and found I had about about $5Ks worth. When I started culling and making those hard choices I found I kept the better 1.25"s and let the 2"s go. I still have cull some more....

Most of the EP that I use for the 6" & 8" SCTs are 2" EPs so that is why both of them have been converted to 2".
