M42 to M42 extender
23 March 2021  | 

I purchased this extender to replace one I had modified to an M48 (female) to M42 (male) 21mm extender to fit the field flattener (PlanoStar x1) of my f7 APO refractor to give the correct back focus for my ASi533 OSC Cooled camera. As there were no other 48(f) to 42 (m) extenders.
My ASi533 kit is now back to normal, the extender is an exact match to the one I modified.
