Since their introduction in the US market a few years ago, the GSO SuperView series of wide-field eyepieces have taken the amateur astronomy community by storm. These are, by far, the best-selling GSO eyepieces.
This 30 mm SuperView eyepiece has an apparent field of view (AFOV) of 68 degrees, so users will experience incredible views without breaking the bank or impinging on your scope's balance. This 30 mm SuperView eyepiece has 2” barrel.
Images are virtually free of chromatic aberration or pincushion distortion with excellent flatness of field and eye relief. This eyepiece features rubber grips on the housing and foldable rubber eyeguards. It is also fully multicoated, has blackened lens edges for improved contrast, and comes with two end caps.
