|Description:||I wanted an inexpensive low power 2" |
eyepiece to look at broad vistas in my 8" f4.7 Newtonian so purchased the GSO Superview 30mm. It is finished well and the viewing is good. Centre 1/2 of field is sharp ( about all you can expect for EP in this price range ) but contrast is good. Gave a great view of the entire double cluster in Perseus.
I feel I got good value for my money.
