Hi Barry
Sadly, like me, you have discovered not so! With my WO 80mm EDII and a WO 2” diagonal, most of my eyepieces come to focus using the supplied WO 2 inch extension.
However, for my Baader 21mm Hyperion, I need to use the Televue 3 inch extension tube, and the whole shebang ends up a little shaky as you can grab the extension tube and wobble it up and down. The wobble is in the sheer cantilever effect on the WO focuser, not in the nicely made Televue extension.
Cheers
Dennis
