lol this is getting confusing
From what I can gather (using details from Optcorp)...
-The
old Extender is 1.25" native, using adapters to get up to 2"
-The
new Extender is 2" native.
-The two are not interchangable ie. the old extender cannot be used on new ED OTA etc
Is the barrel size enough to differentiate between the two?
I couldn't find any pics of the new extender, however
here is a photo of the older extender on a 106N.
