Been toying with the idea getting one for my reflector. But I'm worried it won't work because I'm using a pretty low profile helical focuser. I'd have to be careful there wouldn't I ? About not achieving focus I mean without moving the primary towards the focuser? A crayford only has 1" of travel, is this correct? What's the profile of a crayford? ........What did you have for lunch on the 20th of may EL??
