Frequently Asked Questions

1 - 3 of 3

Q1: 1. How does the reducer connect to a Celestron Nexstar 5" Smt.Cass.? 2. Also, can this item also be used at the same time that a rear mounted light pollution filter is being used? Thanks

A: The reducer corrector will fit right on the back of the scope itself. Because of where it is on the scope you can definitely use it in conjunction with a light pollution filter.

Q2: Is that reducer compatible with the new nexstar c6?

A: It should work fine with the C6-S.

Q3: Can i use the reducer with my NexImage camera and with normal eyepieces (1,25")??

A: The Celestron Reducer/Corrector f/6.3 can be used both for visual observation and astrophotography with the NexImage imager.

Celestron Reducer/Corrector f/6.3

This combination focal reducer and field corrector lens accessory works with all Celestron 5", 8", 9 1/4", 11" and 14" Schmidt-Cassegrain telescopes. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality. The Reducer/Corrector is f/6.3 for C5, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope.

If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, it reduces exposure time by a factor of 3.

Celestron doesn’t offer a f/6.3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6.3 Reducer/Corrector. Results are amazing both visually and photographically.
