Celestron f/6.3 Reducer Corrector (94175)

A really necessary accessory for astrophotography

I use it for my Celestron C8. It expands the field of view of the telescope, reduces the focal length and flattens (not completely) the edges of the image. Required for Schmidt-Cassegrain telescopes, especially if they take photos and do not have self-guidance. It also works for visual purposes as it allows a larger field of view for large nebulae and galaxies as well as allowing the telescope to capture more light. The quality in terms of function and materials is very good, the price, like everything in astronomy, is a little high.

Reducer works great.

I have an 11” Celestron telescope and recently purchased a Celestron f/6.3 Reducer Corrector to help with my astrophotography. The corrector was very effective at significantly reducing the exposure time of my images. Also, it gave me a wider field of view which is helpful in making sure I got the whole target in my image. The stars were round and Sharp, except at the edges of the image. Lastly, although there is some vignetting at the edges, it doesn’t affect processing the target as I’m able to crop the edges of the image.

Unfortunately I haven't had a clear sky for some time. Can't wait until I can!
