About this product
Excellent value, high quality 2" Photo-Visual Coma Corrector
Modular coma corrector designed for fast Newtonian Telescopes from f/3-f/6 but specifically optimised for around f/4 that can be used both visually with eyepieces and for astrophotography.
Reduces coma and field curvature.
Nicely made with large thumbscrews and a brass compression ring that won't mark your eyepiece barrel.
The eyepiece holder can be removed revealing an M48 thread to connect to a camera and also includes an M48-M42/T2 adapter.
Increases magnification slightly (approximately 1.1x) and has a back focus requirement of 75mm which means you may need to use additional spacers with eyepieces or cameras to achieve the correct distance.
