Celestron Reducer Lens .7x for EdgeHD 800 Telescope

The Celestron Reducer Lens .7x for EdgeHD 800 Telescope reducers features a custom 4-element optical design engineered to maintain the flat-field performance of the award-winning EdgeHD optical system. Unlike generic reducers, the premium reducers provide substantial back-focus to accommodate an assortment of imaging accessories. EdgeHD reducers offer high-index optical elements, including extra-low dispersion, exotic Lanthanum elements, which provide high contrast viewing while minimizing chromatic aberration. All air-to-glass lens surfaces feature multiple layers of coating for maximum light transmission and color correction and contain blacken edges to minimize internal reflection and maximize image contrast. Incorporating computer assisted CNC machined aluminum housing, for precise spacing and alignment of optical elements, and threaded metal covers on the lens assembly to protect your investment from dust and scratches, the reducers offer you an outstanding mechanical design. With the Fastar option on all EdgeHD optical systems, coupled with the .7x reducer, your telescope becomes the most complete imaging system available in its price range today.

Design

4-element optical layout designed specifically for the EdgeHD 8-inch to maintain the flat-field performance of the EdgeHD 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-Percent

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.
