I am looking for a GSO 10mm Superview. Does anyone own one. What are it's plus and minus.

Thanks.

I do. It's a very small, lightweight eyepiece, about the size of a 13mm Plössl. The eye relief is a bit on the short side, but not too bad. About the level of a 10mm ortho, but with a substantially bigger eye lens. The lens is not deeply recessed, and the entire field is visible (not when wearing glasses!), though you may need to fold the soft rubber eyeguard down. The apparent field of view is at least 70°, but feels closer to 75°. 

 

It's quite darned sharp, with good contrast, and appears to be multicoated. Edge performance is very decent, even in faster scopes. In slow scopes, it's excellent. 

 

The design is NOT a classic Erfle, but a weird 1-1-1-2 design (yes, I've taken one apart). It Barlows well and works well in a binoviewer.  

 

It was the first short focal length, wide-field eyepiece I got, and it opened new horizons for me. I found it much easier to use at high magnification than the 10mm Zeiss Jena Ortho I had previously been using, since the larger field allowed more stars in the field, giving many more reference points for faint deep-sky objects, as well as allowing extended drift time, when observing with scopes without tracking. 

 

It's similar to the Masuyama 10mm 85° in many respects, which has given me hope that this eyepiece can actually work for me, despite reports of it having troublesome eye relief.

Thank you for the report. Agena told me they will start carrying them later this month. Where did you get yours? I really like the superviews in my CC6.

I bought mine many years ago from TS. I've had them for at least ten years. 

 

All the Superviews are really good in long focal ratio scopes. The 20mm will show any dust on the front lens, which is super annoying for lunar observing. A shame, since this eyepiece works extremely well in binoviewers. For deep sky, the dust is not an issue.

The 10mm SuperView that GSO introduced about a decade ago wasn't nearly as good as the others in the series. Production was discontinued shortly thereafter.

 

The one coming early next month is a new iteration, and while we do have the new 10mm on the way, we do not have any specs yet.

 

Sincerely,

Sign me up for one....I would love to test it out!

Interesting. I considered the 10mm to be one of the best in the original series. It was most certainly my most used one. It even did fairly well on my f/5 Dobsonian.
