Has anyone got any recent news on the supposed release of a FR from Celestron for EdgeHD scopes?
I have just spent the last of many nights testing a possible solution manufactured by Optec called the Lepus .62 reducer said to be suited to HD optics. Sadly, and despite some amazingly helpful co-operation from their CEO Jeff Dickerman, it seems that the Lepus re-introduces major off-axis coma no matter how careful you are about placement, spacings etc. Dickerman even sent me over a prototype for a modified mounting system for the Lepus as a last resort and a newly housed lens system. But it didn't work as it should and sadly, is on its way back to Optec.
I've been lent an AP telecompressor thanks to the generosity and patience of Gary Beale that I hope I can get enough sky to test tonight but it's a refractor design and I'm not expecting miracles.
So at the moment, I'm in the position where the sexy optics of the EdgeHD system are probably only good for visual use or for imaging at F11 until Celestron get their optical act together. I can swing my HyperStar back onto this scope but what a waste. I've reserved that to use with my plain-Jane C14 as soon as my PMX arrives.
Does anyone have any glimmer of hope to offer?
