  • Expressly manufactured for the Celestron EdgeHD 800 telescope, this .7X Focal Reducer reduces your exposure times by half!
  • The Celestron .7x Reducer Lens for the 8" EdgeHD is made of rare earth Lanthanum glass, which minimizes chromatic aberration and yields clear, sharp views.
  • Generous (105mm) back focus allows you to attach other imaging accessories, as well as T-adapters without losing the ability to come to focus.
  • The Celestron EdgeHD 800 Reducer increases the field of view by 43%...and a wider field of view means you can image larger galaxies and nebulae and still get some background sky in the frame.

Celestron EdgeHD 800 .7X Focal Reducer

The Celestron EdgeHD 800 .7X Focal Reducer features a custom 5-element optical design engineered to maintain the flat-field performance of the EdgeHD optics. Unlike generic reducers, this premium reducer provides substantial back focus (105mm) to accommodate an assortment of imaging accessories.

The EdgeHD 800 reducer offers extra low dispersion, exotic Lanthanum elements which provide high contrast viewing while minimizing chromatic aberration. All air-to-glass lens surfaces of the .7X Focal Reducer Lens features multiple layers of coating for maximum light transmission and color correction, and has blackened edges to minimize internal reflection and maximize image contrast.

The aluminum housing of the focal reducer has been designed and CNC machined for precise spacing and alignment of the optical elements. Threaded metal caps are included as well, which will keep your reducer safe during storage and transport.

Celestron EdgeHD 800 Focal Reducer Highlights…

Design: 5-element optical layout designed specifically for the EdgeHD 8" to maintain the flat-field performance of the Edge HD optical design

105mm of back focus: Provides generous back focus to accommodate additional accessories and a wide variety of cameras. Also allows use of existing T-adapters for EdgeHD 800 and other Celestron imaging accessories.

One full F-Stop faster than f/10: Reduces the exposure time by one-half to capture the same brightness of object.

Increase field of view by 43%: Better for capturing wide field images of larger galaxies and nebulae.

Lanthanum Glass Elements: EdgeHD reducer uses "rare earth" Lanthanum glass elements for clear, high contrast viewing while minimizing chromatic aberration.

Fully multi-coated lens elements: All air-to-glass surfaces have multiple layers of coating for maximum light transmission and color correction.

Blacken edges: All lens elements have blacken edges to minimize internal reflection and maximize contrast.

Optimized for APS-C sized sensors: Including most DSLR cameras and Nightscape CCD cameras

Machined aluminum housing: Computer assisted CNC machined aluminum housing for precise spacing and alignment of the optical elements.

Threaded metal covers for both ends of the lens assembly: To protect your investment from unwanted dust and scratches.

Versatility: Provides an intermediate focal length between the telescope (f/10) and the optional Hyperstar accessory at f/2, making the EdgeHD the most complete imaging system in its price range.

Questions & Answers

Product Questions

Hi. Do you have a T-adapter solution for this reducer to use filter? I have EdgeHD 8", this reducer, T-adpater for HD. I'd like to add filter(s) to my astrophotography setup, but Celestron doesn't have a solution now with their own products.

Will this reducer work with my Celestron C8 OTA? I'm imaging with a Nikon D800 and would like to increase my FOV. I also have a OPT Crayford focuser in the optical train.
