Second generation WideField telecompressor design with 0.5X reduction. Re-design of Optec’s WideField reducer provides improved color correction and longer back-focus. Provides unvignetted field approx. 18mm in diameter. Now compatible with SBIG’s CFW-8 color wheel.
(NOTE: Order NextGEN CCD camera mounting plate separately.)
The Optec NGW (Next Generation WideField) telecompressor increases the effective speed of the Meade and Celestron Schmidt-Cassegrain telescopes from f/10 to f/5. This 1/2 times reduction in focal length allows for 4 times greater field area and 1/4 reduction in exposure time for extended surface objects such as bright nebulae. The system is optimized specifically for f/10 Schmidt-Cassegrain telescopes to allow for correction of the field curvature and spherical-chromatism that afflicts these types of instruments. At f/5, the maximum corrected field has a diameter of 17.5 mm at the image plane which makes the optic suitable for CCD cameras with imaging chips of the same diagonal dimension or smaller.
