About the Sky Mentor 2"-1.25" Compression Adapter...

Finally, the deluxe Sky Mentor 2"-1.25" Compression Adapter is available for sale independently! For years, astronomers with 2-inch diagonals have been scratching their eyepieces every time they fasten them into place with a set screw. Well, no more.


The most attractive feature of the Sky Mentor 2"-1.25" Compression Adapter is the brass compression ring which grasps eyepieces round their entire diameter when tightened, without marking the surface whatsoever. Replace the 2-inch adaptor you already have with a Sky Mentor. It''s not expensive, and it will protect the value of your most expensive eyepieces for the future.



Sky Mentor 2"-1.25" Compression Adapter Features...


  • Reduces a 2" focuser down to accept 1.25" eyepieces and/or accessories



  • Brass compression ring keeps adapter from marring eyepiece barrels



  • Replace your old adapter inexpensively!
