It's like having a whole box of eyepieces in one!

Sophisticated optical design; all elements are multi-coated. Anti-slip retention groove in the nosepiece. Deep, comfortable rubber eye cup. Lovely smooth action gives this eyepiece a great quality feel.

Customer feedback:

I recieved the zoom eyepiece I ordered the other day and have been using it with a Coronado PST Ha solar telescope. The sun was absolutely brilliant! I have never seen it look so sharp and clear at all magnifications!
