365Astronomy 1.25" SCL Self-Centering-Lock - Self Centering Visual Back 2" to 1.25" with M48 Female Thread

365Astronomy 1.25" SCL Self-Centering-Lock - Self Centering Visual Back 2" to 1.25" with M48 Female Thread
It is practically a 1.25" eyepiece holder (also called visual back) that can be plugged into a 2" eyepiece holder, thus effectively converting 2" into 1.25", but with quick locking and self centering ability.

It could also be attached to (screwed onto) a male M48 thread, although if that is the main purpose then we also offer a shorter version with an M48 female thread. Click here for that version...
