Hi Chris,

It would help us to help you if we knew a couple more details about your Celestron Eyepieces: What focal length(s) of eyepieces do you have that you might want to use with a Barlow ?

For example: if you have a 24mm eyepiece, a 2x barlow will make it seem like a 12 mm eyepiece. And it follows that a 32mm eyepiece would work like a 16mm eyepiece with the same 2x Barlow.

Ed
