    Default GSO Superview 1.25" EP's



    Does anyone have any experience with the GSO Superview EP's. I found two( 15mm and 20mm) for what seems to be a fair price and was wondering about the quality of the optics, and if they would perform well in my Z-10 dob. I'm very new to the hobby but loving it. I have a limited budget, but I'm trying to expand my EP collection ( currently 9mm and 30mm). Any help or comments will be greatly appreciated! Thank you.

    The 30mm that came with your Z10 is a GSO Superview.

    These aren't the best in a faster scope and you will get some coma around the edges. They are certainly serviceable in the center of the FOV. These perform quite well in slower optics.

    I used my 30mm (same as yours) to observe the entirety of the Messier catalog and made a good start on the Herschel 400 list.

    All that to say, they should provide a good image in the center, but expect coma around the edges of the FOV...

    These are an Erfle design and will not work well with your fast Dob. They do work well in slower scopes like SCTs. But you will be disappointed with them in your scope. For an affordable EP that will work well, I would recommend the Celestron X-Cel LXs. If you want EPs that REALLY perform well, look at the ES 82s and 68s.

    They are just fine in an f10 CAT. I don't use them for my f5 DOB. In my f5 12" I use Panoptics and ES100s depending on how much AFOV is desired.

    I agree with others. 15mm and 20mm Superviews will be poor match for your DOB. If you looking for budget EPs to start observing you will be better off with Plossls. If you are ready to invest in better quality EPs Celestron X-Cel LXs or ES 68 and 82 will surve you well, as Ozman suggested.

    There are a few other EP lines which come close to X-Cel LX in performance, but could be find for a bit less $, in particular if you buy used: Starguider Dual ED 60 degree (sold under many brands), Zhumell Planetary LER 55 degree (again many re-brands available), BST/TMB Planetary 58 degree.

    Thank you all for the advise...I guess I'll be looking at EP's other than the GSO's......Maybe I'll just hold off until I can sweet talk the Treasurer into increasing my budget. Thanks again!

    Trying candidates at a star party is a good idea. I didn't. As a result I bought sets of 83* AFOV eyepieces before I discovered I really don't like that format. Advice is nice but try before buy is better.

    I'd like to contribute to this conversation but the weather gods seem to be laughing at me. I picked up a Meade 5000 UWA 20mm which I can't recommend only because I still haven't yet had a good night to try it out and looks like the next 2 nights will be no better. I suspect based on what I've read regarding quality it probably performs somewhere around the X-Cels and ES offerings and if you shop hard they can be had for between $99 and $130 depending on FL and vendor.

    On the other hand, I know Bigz just sold a pair and when people ask about budget EP's, he never seems to recommend them before the X-Cels. Don't know what to make of that

    Those Meade EPs I sold, should not take it personally. I just bought, tested and sold Baader Morpheus and a few months ago bought tested and sold TV Delos. It is me, not them
