Hi Mark and thanks. Yes. The HD14 is up on it's Titan and ready to go - I already had a HyperStar but of course hadn't appreciated that the EdgeHD requires a modified HyperStar - so now I'm waiting again while an adapter ring staggers across the Pacific from Starizona.
Because I will have to partially disassemble the HyperStar in order to fit the adapter, I have decided to reassemble it with a 30 thou gap (using feeler gauges) in the hope that this should place it close enough to collimation.

Also, and rather than wait for Celestron to get their reducer act together, I decided to have a crack at the Optec Lepus reducer (.62) that OPT claim is designed for use with the HD optics. It too is 'coming'. If the clouds ever part, I'll let you know how it performs.
