Designed especially for the classic Meade and Celestron SCT’s, the NGM yields an incredible f/3.3 effective focal ratio (EFL) on native f/10 systems. When used with an f/11 classic C-14, the NGM will yield an EFL of f/3.7. Results may vary slightly depending upon the imaging train configuration.  Best results will be obtained when used with a Temperature Compensating Focuser. 17403 – NextGEN MAXfield 0.33X telecompressor for SCT

The second-generation NGM 0.33X Maxfield telecompressor is especially well-suite for most C-mount cameras including the Mallincam Video CCD cameras.

The optical design of the NextGEN 0.33X was performe using Zemax and optimized for four field points using wavelengths of 450, 550, and 650 nm.  The goal was for the smallest blur diameters for the four field points. The system was modele using the actual optical prescription for an SCT with the inherited aberrations of this telescope. The resulting lens curvatures of this design were mading without adjusting the radii to the optical lab’s tool list. Custom tools were mading for all surfaces.

TCF-S focuser,
