This is a decent quality diagonal for most telescopes. It's high enough quality to see the moon's craters and some distant sky objects.

Somebody doesn’t understand what this is for!Where you insert an 1-1/4” O.D. eyepiece is less than 1-1/4”! The eyepiece only goes in about 3/8” - then it’s smaller - didn’t bore all the way out!Hopefully, it’s replacement will be made correctly!
