Correct for unwanted coma in your f/3 to f/6 Newtonian reflector telescope with the Starfield 2-inch Coma Corrector. This handy coma corrector will fix the stretched, tadpole-shaped stars that appear at the edges of your images when using a f/3 to f/6 Newtonian telescope.

Starfield 2" f/3 to f/6 Coma Corrector

Add this Starfield Coma Corrector to your reflector telescope and create a flat image field for more accurate imaging. You won't have to worry about vignetting, this corrector will flatten past the edge of your full frame DSLR or dedicated astrophotography camera. The 2" barrel size nosepiece is threaded to accept standard 2" filters, while the fully multicoated optics eliminate any chromatic aberration.

A brass compression ring securely holds the corrector to your telescope, and is adjusted via two large thumbscrews, with a safety groove. The corrector is comprised of three pieces; a 2" nosepiece containing the optics, with a 48mm male filter thread, a 2" eyepiece barrel, and a M48 - T2 adapter ring. Back focus is approximately 70mm.
