Made from machined aluminum, it enhances image brightness and field of view while correcting edge distortions, offering astrophotographers and observers a versatile, high-quality upgrade for models ranging from C5 to C14. ## Description From the manufacturer About us Celestron has been an optics industry leader for decades, ever since Tom Johnson unveiled the game-changing C8. We strive to continue his legacy by continually developing exciting products with revolutionary technologies. Here, you can learn all about our patented, one-of-a-kind innovations. Review: Useful piece for telescope and camera - Using with a Celestron 8SE telescope and Nikon D5300 (with attachment) to "zoom out" a little when taking pictures of the moon and sun (with solar filter) instead of getting parts of it, it zooms out just enough to get the whole into the frame. Simple to attach to the telescope and then clip the camera on. Has a reasonable amount of weight to it, not too heavy but feels like a quality piece. As with all photography equipment if you can get it on sale the better value it will be. Review: Great for any observer's "tool box". Brighter. Wider Angle - 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. ## Features - Unique focal reducer and field corrector lens accessory - Reduces the focal length and f/ ratio of your Schmidt-Cassegrain telescope by 37 percent - Provides a dual focal ratio instrument without sacrificing image quality - Compatible: Celestron schmidt-cassegrain telescopes (C5, C6, C8, C9.25, C11, C14) - Made from machined aluminum material ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00009XVHZ | | Additional Features | Dual Focal Length Functionality | | Best Sellers Rank | #67,985 in Electronics ( See Top 100 in Electronics ) #35 in Telescope Eyepieces | | Brand | Celestron | | Built-In Media | 1 x Celestron Field Lens Corrector/Focal Reducer, Black | | Coating | Multi-Coated | | Compatible Devices | Celestron Schmidt-Cassegrain telescopes (C5, C6, C8, C9.25, C11, C14) | | Customer Reviews | 4.7 out of 5 stars 703 Reviews | | Exit Pupil Diameter | 31.75 Millimeters | | Eye Piece Lens Description | Plossl | | Eye piece lens description | Plossl | | Field Of View | 0.04 Degrees | | Finderscope | Reflex | | 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… | | Focus Type | Manual Focus | | Global Trade Identification Number | 00050234941754 | | Item Dimensions D x W x H | 5.1D x 5.1W x 5.1H centimeters | | Item Type Name | Field Lens Corrector/Focal Reducer | | Item Weight | 150 Grams | | Manufacturer | Celestron Acquisition, LLC | | Manufacturer Part Number | 94175 | | Model Name | Celestron f/6.3 Reducer/Corrector | | Model Number | 94175 | | Model name | Celestron f/6.3 Reducer/Corrector | | Mount | Equatorial Mount | | Objective Lens Diameter | 200 Millimeters | | Objective lens diameter | 200 Millimeters | | Optical tube length | 105 Millimeters | | Optical-Tube Length | 105 Millimeters | | Power Source | Not Obtainable | | Telescope mount description | Equatorial Mount | | UPC | 050234941754 | | Unit Count | 1 Count | | Warranty Description | 2 year manufacturer | | Zoom Ratio | 7 | ## Product Details - **Brand:** Celestron - **Eye piece lens description:** Plossl - **Model name:** Celestron f/6.3 Reducer/Corrector - **Objective lens diameter:** 200 Millimeters - **Optical tube length:** 105 Millimeters ## Images ![Field Lens Corrector/Focal Reducer, Black - Image 1](https://m.media-amazon.com/images/I/519X+yzPqPL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Useful piece for telescope and camera *by M***T on 20 July 2026* Using with a Celestron 8SE telescope and Nikon D5300 (with attachment) to "zoom out" a little when taking pictures of the moon and sun (with solar filter) instead of getting parts of it, it zooms out just enough to get the whole into the frame.
