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 never had a GSO Superview but the normal pl one are good so should be great

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.

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