Yeah, they're certainly worth what you pay for them. It's a pity that the Meade RCX series of scopes doesn't have the same sort of secondary as some of the other SCT with compatible secondary lens holders. The primary mirror in these scopes is fixed and it's the secondary that moves to focus. Which I think is the better way of doing it. Saves all the mirror flop problems and such with normal SCT setups. It would make using the hyperstar a lot easier... w.r.t. focusing the images and the problems with the primary mirror.
