Celestron f/6.3 Reducer/Corrector

BH #CERC • MFR #94175
Celestron f/6.3 Reducer/Corrector
Key Features
  • For 5-14" Catadioptric Scopes
  • Widens Field of View
  • Shortens Exposure Times
  • Requires 93633-A Photo Adapter
This combination focal reducer and field corrector lens accessory works with all Celestron C5, C8, C9.25", C11 and C14 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, C9.25" and C11 telescopes and f/7.0 for the C14 telescope.

It offers wide fields of view with any Schmidt-Cassegrain telescope.  Used for astrophotography, it reduces exposure times 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 a resulting loss in contrast.

is this thing gonn change lowest useful magnification for telescope if you use it(for example cpc1100’s lowest magnification is 40 how much will it change)
Asked by: david
It does not affect the eyepiece directly. It reduces your telescope's focal length (in your case 2800mm) down to 1764mm. So now your 40mm eyepiece drops from 70x to 44x magnification.

do I need to calculate eyepiece magnification with a reduced focal length or whit normal focal length
Asked by: david
If you are using the reducer in place, it's best to calculate eyepiece magnification with the reduced focal length. For example, if you are using an 8" SCT telescope (203.2mm diameter mirror), you would multiply 203.2mm x f/6.3 = 1280mm focal length. If you're using a 25mm eyepiece, 1280mm / 25 = 51x.
