The Tele Vue 2x Prism Amplifier/Corrector Lens & Flat Coupler is used in combination with the Bino Vue binocular viewer and will correct prism aberrations like spherical, color, and edge of field astigmatism. The faster the telescope system, the greater the need for this corrector.
It maintains simple drop-in installation just like any 1.25" eyepiece, while maintaining optimal optical performance in even the finest, fastest instruments.
This includes the Bino Vue Flat Coupler, which allows space for a filter to fit between the end of the 2x Bino Vue Amplifier and a 2" diagonal mirror without interference.
