JMI NGF-S non-vignetting large format visual back adapter for Meade 16" LX200 SCTs | |
Click image for close-up | |
 |
This adapter is designed to avoid vignetting the photographic image when using a JMI NGF-S focuser with Meade 16" Schmidt-Cassegrain telescopes. This large aperture adapter attaches to the rear cell threads of the scope (replacing its standard 2" step-down ring) to provide unvignetted 35mm and medium format photography. The NGF-S focuser attaches to the adapter in the same way it would attach to the smaller diameter 2" rear cell step-down ring supplied with the scope. CCD imaging does not require this adapter, as CCD chips are smaller than the standard 2" SCT rear cell and cannot be vignetted, as can the larger 35mm and medium format film negatives. An optional light shield (2499-LS) is available for this adapter to prevent stray light from entering the focuser bearing cavity of the NGF-S focuser when imaging from light polluted areas. The 10" through 14" Meade and Celestron SCTs require adapter #2499-10.
