Questions & Answers

Wayne P : Which case would you suggest to transport the scope?
Shopper : Do the rings on this scope close with snaps or with threaded closures? Can't see any photos of the OTHER side of the rings.
ROBERT G : What kind of eyepiece finder scope is needed for the Explore Scientific 127mm f/7.5 ?eric r : I have this scope (carbon fiber tube) and use the straight-through finder, with correct up-down and left-right image (it is on an elevating optical alignment pier and so I had no need for a right-angle prism). Most of the time, however, I used Telrads, one mounted on either side of the tube.
