Review on Celestron C Series Telescope f/6.3 Reducer Corrector by Chris Riley

My main motivation for purchasing was to get the sun (and moon) in the field of view of my APS-C (24 x 16mm) camera sensor using my Celestron 8" SCT (2000mm FL) and frame sensor is not possible because the C8 vignettes.This device also offers a slightly wider field of view and lower f-number for deep sky astrophotography.Handy reference numbers for those who want to photograph an eclipse or just the entire moon: APS-C camera is About 1260mm tall If using a full frame, about 1900. But only if you can center the target and keep it centered.(To photograph the moment of the eclipse, use 400mm APS-C/600mm full frame and no solar) This Device is useless for solar system astronomy except for the sun or moon or when using an ocular projection lens Otography But you can always just take it off A big he advantage of this device is that you get about the same performance as with an Edge HD telescope and the field level costs half as much. When you buy the OTA Edge HD 8" you get a built in field smoother but still have a longer focal length and therefore smaller field of view and slower f-number. To see the full sun or moon or more Pleiades in camera, you'll need to buy another focal reducer, about $300. Since the Edge HD costs $400 more than the SCT, spend an additional $700 to get the same optical setup you get with the SCT plus this item costs about $150. Use this plus SCT and save $550 and you've got even less glass between you and the stars to boot (or rather, a mirrorless camera) from this thing.
