Too late! It’s on its way from Germany.
Are you folks using a baader click lock (if one exists for APM) on the focuser end for heavy binos or are you happy with the default arrangement?
I changed the APM twist lock (or whatever they call it) for a Baader Clicklock, which I feel is a vast improvement. My scope has the 3.7" focuser, and I've also changed to a Baader M84/M68 adapter, instead of the original M84/M63 adapter. The Baader adapter is shorter, and I now run a 60mm long M68 extension tube between the M84/68 adapter and the Clicklock, so I don't have to rack the focuser all the way out. I find the Baader adapters much better mechanically and more elegant cosmetically. When using my Zeiss binoviewer, I use an M68/T2 adapter and Baader Quick-change adapter to securely thread the T2 prism onto the focuser. The binoviewer can never accidentally drop out of the focuser, even if the quick-change adapter loosens.
