## Overview

The Celestron Field Lens Corrector/Focal Reducer is a precision optical accessory designed to reduce the focal length and f/ratio of compatible Schmidt-Cassegrain telescopes by 37%, effectively converting an f/10 system to a faster f/6.3. Made from machined aluminum and featuring multi-coated optics, it enhances image brightness and field of view while correcting edge distortions, making it ideal for both planetary and deep-sky observations. Compatible with Celestron models C5 through C14, it offers easy installation and a 2-year manufacturer warranty.

Review: Excellent optics. Reduces exposure times. Quality manufacturing.
Review: I have Celestron C8, this has a focal ratio of F/10. You don't necessarily need to know what that means but Astrophotographers would describe this as a "slow" ratio. Great for planetary obsevation. For nebulae, star clusters etc, still a great all-rounder, but some nebulae are quite large and/or diffuse. The focal reducer gives F/6.3. (faster). This means a wider and brighter field, though magnification can be applied to it, as normal. The Pleiades are almost all available in a low powered eyepiece, the moon is fully observable. When I went comet hunting, it gave me a better all-around view, before zooming in for the Nucleus and Coma. This may be classed as a luxury item, but it Does enrich the brightness and gives wider angle vistas. There are comments that it flattens the field. This means that at the margins of the view, in an SCT, the stellar points of light, can become slightly elongated. This is corrected with this lens. A good purchase for me, I would recomend, a good astronomer's tool, gives options. Is easy to add and take off the Telescope tube, in low light, thanks to the solid/well spaced screw thread.

| 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… |

Der Reducer macht bei mir alles richtig. Das Bild bleibt zum Rand hin deutlich schärfer und hat keine auffällige Verzeichnung, Krümmung mehr. Bis jetzt sehr zufrieden.
