## Overview

The Celestron Focal Reducer & Field Corrector is a precision accessory designed for Schmidt-Cassegrain telescopes that reduces focal length and f/ratio by 37%, converting an f/10 system to f/6.3. This results in a wider field of view and shorter exposure times, ideal for deep-sky observing and astrophotography. Fully multi-coated for maximum light transmission and housed in durable machined aluminum, it supports all standard SCT accessories and comes with a 2-year warranty and US-based expert support.

## Description

Imagine having two telescopes in one — a long focal length instrument for lunar and planetary work and a short focal length scope for deep sky observing and astrophotography. With the Celestron Reducer/Corrector Lens, that’s precisely what you get. Explicitly designed for Celestron Schmidt-Cassegrain telescopes, this unique lens reduces your telescope’s focal length and f/ ratio by 37%, turning your long focal length telescope into a fast, short focal length instrument. A f/10 focal ratio now achieves a f/6.3, while an f/11 focal ratio now achieves a f/7. For visual use, this means you get lower power with the same eyepiece and a wider field of view. Photographically you also get a wider field and much shorter exposures. The Reducer/Corrector is easy to install by threading the unit onto the rear cell of your Schmidt-Cassegrain telescope (or the reducer plate of the C11 and C14). Once installed, you can add additional accessories like T-Adapters, 1.25” Visual Back, Star Diagonal, or Off-Axis Guider. The Reducer/Corrector can also be used for terrestrial digiscoping. The faster f/ratio allows you to use slower film or shoot in lower light level situations and still properly expose your subject. This fully multi-coated lens provides maximum light transmission with near full-field illumination. The lens is housed in machined aluminum for are machined aluminum black anodized. The internal surfaces are blackened and glare-threaded to provide the highest contrast. The lens has a knurled surface, providing a tremendous gripping surface for threading/unthreading.

Review: Must have. - Excellent optics. Reduces exposure times. Quality manufacturing.
Review: An essential accessory for deep sky viewing or photogrqphy with a Celestron SCT - The focal reducer is easy to screw on and of, and it fits snugly onto my Celestron 8SE. It provides a crisp, clear wider field of view, allowing me to see or photograph a larger area of the sky. It feels sturdy and well-built, with knurled rubber for ease of grip. It is a good value for the money, and recommend it for anyone getting started with a Celestron SCT.

## Features

- LIKE HAVING TWO TELESCOPES IN ONE: Your long focal length Schmidt-Cassegrain is well suited to lunar and planetary work. Add the Reducer Corrector and you have a short focal length telescope perfect for deep sky observing and astrophotography.
- REDUCES FOCAL LENGTH AND F/RATIO BY 37%: Simply thread the reducer onto your telescopes rear cell and an f/10 Schmidt-Cassegrain becomes f/6.3. An f/11 instrument becomes f/7.
- COMPATIBLE WITH ALL YOUR ACCESSORIES: Once the reducer is installed, you can add accessories like a T-Adapter, visual back, star diagonal or off-axis guider as usual.
- GREAT FOR TERRESTRIAL DIGISCOPING: The faster f/ratio allows you to shoot in dimmer lighting conditions and still properly expose your subject. This fully multi-coated lens provides maximum light transmission with near full-field illumination.
- UNBEATABLE WARRANTY & SUPPORT: Buy with confidence from Celestron, a leading telescope brand in California since 1960. Your purchase includes a 2-Year US Warranty and unlimited support from our team of US-based experts.

| Focal Length Description | The original focal length of the telescope, before using the reducer corrector, is not explicitly mentioned in the provided information. However, it can be inferred that for an f/10 system, the reducer corrector reduces the focal length by 37% to make it an f/6.3 system. Thus, if the focal length of the f/10 system is F, then the focal length after using the reducer corrector would be 0.63F (f/6.3… |

### ⭐⭐⭐⭐⭐ Worked well, easy to install
*by J***Y on July 30, 2021*

I put this on my celestron 8se SC telescope with the goal of increasing the field of view (because I have a zwo asi224mc camera with a relatively small sensor area). It was easy to install and worked quite well. Before buying it, I was worried that the focal plane would shift so much that I would not be able to focus within the limits of my focusing knob. But that worry was unfounded and I got to focus easily. I could fit the Dumbbell nebula with enough contextual background in the field of view of my camera. As far as I could tell, I did not observe significant vignetting. My plan is to leave it in the back of the telescope forever and only take it off when doing planetary observation or imaging (which requires higher magnification).
