Comments about GSO GSO 2" SuperView Eyepiece - 30mm:
This makes a great finder EP. It is compact, and lightweight by comparison to similar focal lenght 2-inch EPs. Plenty of eye relief for comfortable eye placement. At f/6, a little soft at the edge of the field. Good value for the money.
Comments about GSO GSO 2" SuperView Eyepiece - 30mm:
I really like the wide views I get with this eyepiece. It is constructed very well, and just feels very well made. The view is sharp and crisp, up to very close to the edge. I has become my most used eyepiece. Excellent buy.
Comments about GSO GSO 2" SuperView Eyepiece - 30mm:
This is by far my favorite eyepiece. The eye relief is fantastic, making it comfortable and easy for me and others to use. The views are crisp, sharp, and beautiful. Touring around a very dark sky with this nearly 2° view is one of my greatest pleasures.
Comments about GSO GSO 2" SuperView Eyepiece - 30mm:
The GSO optics is as good as the optics of the big brand names.
This 2" eyepiece fits perfectly in my also GSO 2" dielectric mirror diagonal . I strongly recommend both.
Comments about GSO GSO 2" SuperView Eyepiece - 30mm:
I purchased the GSO 2" SuperView 30mm eyepiece from Agena Astroproducts a while ago and I've used it many, many times. I mainly use this eyepiece for deep-sky viewing which it is well suited for (especially the larger open clusters, the Double cluster of Perseus is simply stunning through this eyepiece, as is the beehive cluster), the 30mm focal length isn't ideal for planetary viewing. I am really impressed with the suprisingly lightweight design and the views I get from it, they are sharp, crisp and quite wide. I also noticed that the comma problem I usually get (I have a fast 10" Dob) is not nearly as pronounced as I get with my other eyepieces of similar size. Unfortunately I can't comment on the accuracy of the colors as I'm colorblind, however, I haven't noticed any major chromatic aberration with this unit.
If you're looking for fantastic views of the night sky while not forking out a lot of your hard earned cash, then I highly recommend this eyepiece.
