Thanks H. The C8 is an excellent scope, I have really enjoyed it. Unfortunately I can't afford the mount to have the C11, C8 and ED80 all side by side!
I did hang onto it for a while with the intention of being able to swap scopes in the obs, but really that largely defeats the advantages of the obs. So I'd rather see it go to someone who'll use it. I think its a good buy if you take into account the extras for the price, but then I am the vendor!
