Why F4.5, do you intend to use coma correctors, what size secondaries, what diameter focusers and how are you going to allow for interpupillary adjustment....and what is a "fast cooling conical mirror" ?

Hi Joe
My 14" will follow on same design as Paul Shopis's 12" but more lightweighted so no surprises accept I'm going for pushbutton electric collimation using dc servo motors and bits and pieces from Jaycar. You'll want to follow Omaroos progress too, he is building a 12" F5.
The 14.5" Conicals I'm inspired by as Anthony Wesley is getting such good results. My version will use a new rear mirror attache=ment design and there'll be no perforation in the front face. No flotation cell required so another weight saving there
