All,
For sale is my Orion 2" Precision Centering Extension Adapter. This is a 2-in-1 adapter as it can be used as an extension tube and also has a helical tightening system which perfectly centers your item (EP, Camera etc). More details here:

Also prevents any marring to your item compared to using screws to tighten the focuser, as the helical. Yours for
$70 including tracked and insured postage. PM if interested please
