This Lumicon Giant Focal Reducer shortens the focal length of Meade 10, 12, and 14" Schmidt-Cassegrain telescopes. It takes Schmidt-Cassegrain's f/10 optics and reduces them to f/6.3 for beautiful low power, wide-angle views. It features a fully-multicoated, 300mm focal-length, achromatic lens for sharp, crisp images. The 80mm diameter lens used in the Lumicon Giant Focal Reducer will not vignette, yielding the maximum possible field-of-view from your instrument. The eyepiece-side is a standard 2" female eyepiece holder.
Focal reducers shorten the effective focal length of telescopes to provide wider visual fields and faster f-ratios for astrophotography.
Ideal for widefield imaging, and requires a camera adapter and your camera system's specific T-mount adapter.
