2" COMA CORRECTOR |

5700 + 18% GST |
Coma Corrector for Newtonian telescopes from f/6 and slower.
4 element corrector, which provides much sharper images in fast telescopes than the similarly priced coma correctors. Offers good performance at f/4.
An effective Newtonian corrector with better field illumination by M48 connection instead of T2. Upgraded version - better sharpness in the field.
This coma corrector can be placed completely inside a 2" focuser and offers a high grade of correction and a low degree of vignetting. The generous back focus of 70mm allows the use of off-axis-guiders. |
|
M48 thread connection for good field illumination |
Especially fast Newtonian systems suffer vignetting when a T2 corrector is used. The short off-axis-guider can be connected directly and no back focus is wasted by adapters. |
