Collimation Eyepieces for CN-212 Takahashi
Description
This two collimation eyepieces was specially designed for my CN-212 (Newtonian-Cassegrain Takahashi). Used together, they facilitate the collimation of the Newton. The reticle of the eyepiece on the Cassegrain side makes it easy to center the black point of the secondary mirror in the eyepiece on the Newton side. I also added a 42mm thread to the 2" eyepiece so It can be mounted on my Paracorr Type I corrector.
