Astro-Tech Dedicated 0.8x Reducer/ Field Flattener for the Astro-Tech AT80ED

This Astro-Tech 2" 0.8x reducer/field flattener is designed for astrophotography while using your Astro-Tech AT80ED refactor

This Astro-Tech #AT80EDRF 0.8X reducer/field flattener is designed for prime focus astrophotography with your AT80ED refractor. (model year 2018 and newer) 

The dedicated fully-multicoated Astro-Tech AT80EDRF converts the 560mm focal length f/7 Astro-Tech AT80ED refractor into a 448mm f/5.6 lens for faster and wider field astronomical and terrestrial photography..

In addition to reducing the focal length of the telescope and thereby increasing the photographic speed, the AT80EDRF flattens the normal field curvature inherent in all refractors to provide images that are focused out to the very corners of a large format DSLR chip. Stars look sharp and point-like all the way across the field in your images. You don't have to worry about photos that are sharp in the center and blurry at the edges.

The Astro-Tech AT80EDRF reducer/flattener slips into the AT80ED focuser leaving you with a very easy connection. The telescope-side barrel is threaded for standard 2" filters so you can attach a light pollution filter if the mood suits you. The camera side of the reducer uses a 42mm T-threads to connect to a T-ring and camera body.  Back focus is 55mm from the shoulder of the reducer to the image plane, the standard spacing for 35mm and DSLR camera bodies.
