The Tele Vue Paracorr type 2 coma corrector eliminates or reduces coma in reflector telescopes as fast as f/3. Works visually or photographically, and the top is tunable to optimize the performance with any eyepiece and telescope combination.
The Tele Vue Canon wide t-adapter provides a larger clear aperture to minimize vignetting through Canon brand DSLR cameras. 25% greater aperture, and features the very stable and secure standard canon bayonet attachment.
