Thanks Laurie, I've been sweating on the StarTrack guys to get it here safely as there are no more available anywhere to replace it if damaged....
Test fitted the Baader ClickLock, Baader BBHS Diagonal and Pentax XW10,
as well as the BV setup of Baader ClickLock, Zeiss T2 Prism, TV Binovue and Tak LE24s.
Just have to wait patiently for some rings or a clamshell........ or make some out of plywood...
