Hi there, I am purchasing a Celestron 11inch schmidt cassegrain with XLT coatings this week. But I have no become frustrated as to whether to purchase the C11-SGT (XLT) or the CPC 1100 GPS (XLT). I have come to the conclusion that the German Equatorial mount on the C11-SGT is far more efficient than the tripod on the CPC. But the C11 is less costly than that of the CPC. Can a person with the knowledeable expertise of cassegrains point me in the right direction please. And how would you compare a Celestron 11inch Schmidt cassegrain with a Meade 12 inch Schmidt cassegrain, because the celestron is more costly than the Meade even though its size is smaller. Thank you.
