Product Description

This Astro-Tech #ATREDT15 0.8X focal reducer/field flattener is designed specifically for prime focus astrophotography with the Astro-Tech AT115EDT EDT apo refractor. While it may also work well with other brands and models of f/7 refractors that use a 2.5" focuser, its performance with other scopes is not guaranteed.
The fully-multicoated Astro-Tech #ATREDT15V2 reducer/flattener converts the 805mm focal length f/7 Astro-Tech AT115EDT refractor into a 644mm f/5.6 system 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 #ATREDT15V2 flattens the normal field curvature inherent in all refractors. This provides images that are sharply focused out to the corners of DSLR and CCD imaging chips. 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 #ATREDT15V2 reducer/flattener threads into the focuser, or camera angle adjuster for a secure connection.  The threading is metric 63x1.  
The camera side of the #ATREDT15V2 reducer has 48mm T-threads to connect to a T-ring and DSLR camera body. A slip-on soft rubber cover protects the T-threads when the reducer is not in use, while a second slip-on cover is provided for the 2" scope-side barrel. Back focus is 55mm from the shoulder of the reducer to the image plane, the standard spacing for DSLR camera bodies.
