Astro-Tech At152EDT .72X Reducer Field Flattener

The Astro-Tech AT152FF 0.72x focal reducer/field flattener is designed specifically for prime focus astrophotography with the AT152EDT triplet refractor.

The fully-multicoated reducer/flattener converts the 1216mm fl 152EDT into an 875mm f/5.76 photographic system.

Not only do you get to speed up your scope, it will also flatten the normal field curvature inherent in all refractors.

Installation is simple. Just unthread the 2" adapter from the focuser drawtube. This will expose the 92mm threads. Now, just thread the AT152FF in its place and you are ready to go.

The camera side of the reducer has 48mm t-threads, so make sure your t-ring will work.
