    Default GSO SuperView Series?



    Does anyone know anything about the GSO SuperView eyepiece configuration?

    Guan Sheng Optical

    I know the 15mm version has a 68° AFOV with a 13mm eye relief. It also has 4 lens elements in 3 groups.

    I’m guessing some form of modified Kellner. Any thoughts anyone?

    recent GSO dob owners like myself probably all posses the 2" 30mm Superview re-branded to some degree or other, which almost universally they all seems to love. I know I do. According to my google skillz they are described as being an Erfle design which features 5 elements in 3 groups, with the exception of the 15mm as you have noted above, which only has 4

    Yup, the 30mm SuperView 2" is an Erfle design, works pretty well, in my opinion. Alan (KT4HX) pointed this out to me when I had the same question.

    I am thinking Konig. You can get ~70 deg FOV in Konig, but I never heard of 70 deg Kellner.

    I think mostly they are some form of Erfle, the 15mm seems to be a bit different though.

    A Konig would fit the configuration of the 15mm.

    4 elements in 3 groups is a Konig I & II design but they normally have a small FOV. The Konig widefield has a 65°+ FOV but has more elements.
    Maybe it is a fallback to a Bertele

    Yes, I was thinking about the Bertele as a contender.

    I'm curious about the 15mm, primarily as I've ordered the Revelation badged version of the SuperView.

    I had the 20mm. Edge is out of focus in f/5 scopes. Trying to get more out of less just does not work for fast scopes. Worked well in a f/12 scope but again the very dimmest stars seen with the ES 20mm 68 degree were not visible in the GSO.

    I've read that the outer field isn't good in fast scopes. I ordered the 'Revelation' 15mm primarily for use with a 130mm f/6.9 Newtonian. I wanted a wide angle EP for 60x (2.1mm exit pupil) mainly for emission nebulae and some other DSO's used in conjunction with an Astronomik UHC-E filter. The UHC-E doesn't have M28.5x0.6 threads and won't properly thread onto my TV Panoptics or Baader Morpheus. As the Astronomik filter fits every other GSO eyepiece I own I reckoned that it should fit the SuperView. It may not. Either way the SuperView cost me 28 quid, which is eight and a half times cheaper than a 19mm Panoptic!
