    Default 42mm GSO SuperView for an Orion ST80?



    Ive been buying some moderately priced 2 eyepieces for my Orion ST80. I have already purchased a 28mm Sky-Watcher LET and a 19mm Celestron Luminos.

    I was considering an eyepiece of around 40mm for low power sweeping and as a kind of finder. Im thinking about something like the GSO 42mm SuperView rather than a Plossl type.

    The 42mm SuperView will give a 9.5x magnification at nearly 7 (6, 50 if my maths is right) TFOV with an 8.4mm exit pupil.

    Im not sure how it will perform in an f/5 short tube achromat however. Im not expecting Nagler or Panoptic type sharpness right to the edge, but at only 9.5x magnification Im supposing it should be OK.

    Does anyone have any thoughts?

    I don't think it will be a happy experience. I know for a certainty I'd never try that. I've done that experiment.

    The fact that the magnification is low won't help with the edge of field fuzziness that you'll experience. That fuzz results from putting a fast light cone through an eyepiece that is not designed to handle it. Plus, with an 8.4mm exit pupil.... even if your eyes dilate to 7mm you'll be effectively stopping down your 80mm scope to 67mm.

    Main point is that if you expect the low magnification to help, it surely won't.

    I agree with not_Fritz. I have that eyepiece and I have tried it in my f5 dob (I got it for my CPC800: f10). It is surprisingly good for the (very cheap!) price, but don't expect it to be sharp outside the central 50% of the field- and as noted you are wasting light anyway. I think 32-35mm is about the longest FL you can use fully in an f5 scope. (The 32mm TV plossl would work very well, with a quite sharp 4 degree field).

    All the best,

    Dean

    Thanks, I suspected this. I was thinking that it might be good for my 235mm SCT as well and I could kill two birds with one stone. I was also concerned about the 8.4mm exit pupil with the ST80. My night vision is very good and I can get very good dilation, but 8.4mm is unrealistic. So no, it wouldn't be a happy experience.

    Thanks Dean, I have a 1.25" 32mm TV Plossl. I'll have to have a look at some wide angle 32-35mm 2" eyepieces.

    The 30mm SuperView looks more promising, but I might be better off with a 32mm GSO Kellner.

    I'm now considering a 36mm Baader Hyperion Aspheric.

    374734ef-fa49-414c-bb17-d215a5b2df57.jpg

    This would give me 6, 28“ TFOV with a 7.2mm exit pupil for 11.1x.

    Has anyone used a Baader Aspheric in an f/5 achromat?

    I've used them in an f5 Newt. They are much better at f10.

    At f5 I prefer Plossls or Panoptics, ES100s. If you like 80* AFOV you might try Naglers or ES. F5 demands very good correction so $$$$$$.

    I am using 31mm and 36mm Baader Aspheric in my Orion 120mm F5 achro and happy with performance. I also have GSO SV 30mm and 42mm . While SVs perform reasonably well in my 8" SCT, I feel that Baader Aspheric deliver better quality views in both scopes. Baader Aspherics have better contrast, less light scatter and more comfortable eye relief. I find ER of GSO SV 42mm is a bit too long for comfortable viewing.

    Baader also have very good light transmittance. Works great on faint stuff.

    I don't see edge softness in Baader. Either it is not bad or my eyes compensate. I do believe they are better corrected than SV since I saw field astigmatism in 42mm SV even with my F7 APO.
