20mm GSO SuperView?

#1

Post by pakarinen »

Thinking about trying one of these to keep plugged in to one of my f5s for fast grab-n-go use when I don't want to take out my EP case. Pretty inexpensive. Experiences or comments?

I have the 30mm 2" Superview from Zhumell (GSO), Offers wide fields - maybe a bit of coma on the edge of the field of view at least through my Dob which was F/4.9. I also use it as a "default" eyepiece on my AR 152 which is a bit more forgiving at a longer focal length. Good for DSOs I would say. Also it is a modified Erfle design, FYI.

GSO Plossl will perform better in a fast frac, but if you are after wider field, Superview would serve. I remember some coma at the edge and excessive light scatter on bright stars.

I had on loan a 20mm GSO Superview to use on my AT80ED f/7 and it provided good views. I am considering getting the 15mm and 20mm GSO Superview for one of my travel kits. I have an ES-62 20mm and am happy with that one, but I may need another travel kit because my granddaughter is now viewing.
*I love the price on these GSO's and am very happy with the loaner. At f/7 in my AT80ED they performed.
Telescopes: *Celestron DX5 SCT 127mm 5" w/StarSense *Astro-Tech 80ED AT80ED
Eyepiece: AT-UWA 4/7/10/13/16, AT-PF 5.5/15.5/25, ES52/10, ES62/20, SvBony 26-70 2", 7-21/3-8 zoom, Bresser 30/35 2"

Good to know. I'd be using one with my AT72ED and a couple other scopes.
