I might have misidentified my question about C6 diagonals. I actually have a good 1.25 diagonal. What I dislike are the little set screws on the visual back and on the EP side of the diagonal. There are 1.25 diagonals available with quick lock, clicklock or other designs for the EP side. However, it seems you need at least one or two moderately expensive components on the telescope side to achieve quicklock stability. Either a SCT to 2" adaptor with a quicklock or SCT to M48 adaptor to quicklock or other adaptors. Any ideas on this? Williams may make one but out of stock or production, Baader is very expensive.
Really prefer a quicklock to a direct connect 2" diagonal. Thanks.
