    Ok so, I got a bunch of barlows and EPs from my Astronomy teacher but in .965 size. My Celestron 130 AM uses 1.25inch EPs. So What I did was take a peice of PVC coupler, and Grind down one end just enough for it to fit snuggly into the focuser. After painting it a flat black and all, I started to think, is this even possible? To go from 0.965 on a 1.25? I think I may have just waisted my time.


    Is this a functional idea? Can I use .965 EPs on a 1.25inch focuser?
    Years ago I made a similar adapter to allow the use of 1.25" eyepieces in a microscope. It works very well.

    Ff you happen to have an older scope these Hybrid diagonals are just the ticket.

    Hi jim , What sergio was saying is he made a "drop in" adapter like lumicon makes . Basicly it just necks down his diagnoal so a .965 eyepiece will fit and be able to view . I think what you were saying is the reverse by using a 1.25 eyepiece in a scope that has a .965 focuser or visual back . I have an older meade scope that has a .965 visual back and i had to buy a hybrid diagnoal so i could use my 1.25 eyepieces with it .

    Yup my bad, I should have read the complete post before responding. DUH!!

    I had that issue with a small reflector. I mucked around with jury rigging an eyepiece adapter but I wasn't satisfied.

    So I bought this adapter, for 20 bucks it's was well worth it

    Well all went good with the adapter and smaller EPs, but now after cleaning up the old EPs, when I go to see throug them in the scope, I have the Comet effect on every object I look at. I used Isopropyl 70% and as ive read, it wont harm the lenses.

    Can it be I screwed them up? Or mabey I placed them in the wrong way? I replaced the very bottom lens with the bulge facing downward. Is this correct?

    Well Sergio I highly suspect that you have assembled the things the wrong way round. Most EPs have the convex (Bulge) up in the bottom lens.

    Have a look at this web page. If you scroll down you'll find a chart showing all different types of EPs and their lens configurations. See if you can locate something like what you have
