optical glass variable polarising filters reduce the amount of light entering your eyepiece

Baader 2 Inch Nexstar Locking Ring C14 A Lost in Space AlgorithmBaader 2" Nexstar Locking Ring Allows direct connection of Baader 2" Zenith Prisms and mirrors to Schmidt Cassegrain telescopes. For Celestron SCTs 8 9. 25 11 14 with female 2" thread (5 mm optical length) For space efficient connection of 2 "accessories to the large NexStar telescopes just the 2" screw housing directly at the telescope. In this way you gain 20% field of view and you can connect for example binoviewers with the help of our 2" prisms
