    Default New Eyepiece



    Hi everybody, your opinions please. Thinking of purchasing a Skywatcher 1.25" 5mm, long eye relief eyepiece 58 Deg' field of view. Just trying to improve on what I have got. Using Kellner 9mm & a SR 6mm in my 114/500 Dob.Will the above mentioned eyepiece help, or am I wasting my money?

    That's the UWA Planetary eyepiece, yes? These seem like a decent price - but best to see if you can find some reviews. Certainly the eye relief at 16mm and the quality will be big leap from what you have now. Depends on your expectations of the eyepiece though?

    SR stands for Symetric Ramsden. The 5mm should work fairly well in your scope, if you can I would recommend replacing the Kellner and Ramsden when you can they are designed for much slower scopes.

    Hi Falcon. Wow, I didn't realize that some telescopes still come with AR (Achromatic Ramsden), SR (Symmetrical Ramsden), and K (Kellner) eyepieces anymore. The standard today is the four element symmetrical Plossl eyepiece. I did have a 40mm Kellner eyepiece many years ago, and it worked fairly well with my Cave Astrola 10" f/5 Newtonian. And, the Kellner triplet design is still used today in some binoculars. I generally never go below a 9mm eyepiece with any my telescopes, due to their long focal length. However, this 5mm eyepiece that you describe looks to be quite usable with your telescope. Also, if you are anticipating on getting more eyepieces on a budget, I can recommend that you look at these 70° and 80° eyepieces from University Optics, at:

    Eyepieces - 1 1/4" Oculars from University Optics

    I have dealt with Jay Seyfried since 1974, and have never been disappointed. He doesn't get a lot of play on the forum here, but he always has top quality optics for sale at very good prices. I hope this helps Falcon, and the best of wishes on your eyepiece purchases.

    I agree on the quality of the eyepieces from University Optics. I have a couple and I'm very happy with them. The price was right too!

    I still have a 20mm Kellner it was part of the 70mm konus (quite an old scope) it worked fine but when I tried using it in the reflector F5 it was not , so as Gabby said the Kellner is not ideal for your scope.

    I have just noticed that Gabby is almost on 2000 posts It seems like the other day when you posted about your 1000 post achievement wow.
