New Astro-Tech focal reducers and field flatteners have been announced by Astronomics. These new reducer/field flatteners are designed for prime focus astrophotography with specific Astro-Tech refractor telescopes.
In addition to reducing the focal length of the telescope and thereby increasing the photographic speed, these new Astro-Tech reducer/field flatteners flatten the normal field curvature inherent in refractors to provide images that are focused out to the very corners of a large format 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 reducer/flatteners thread into the focuser for a solid connection. The telescope-side barrel is threaded for standard 2″ filters so you can attach a light pollution filter. The camera side of the reducer uses 48mm T-threads to connect to a T-ring and camera body. The back focus is 55mm from the shoulder of the reducer to the image plane, the standard spacing for 35mm and DSLR camera bodies.
There are four new models of the Astro-Tech focal reducers and field flatteners designed to fit specific Astro-Tech refractor telescopes which include:
– AT80ED .8x Reducer/Flattener: The dedicated fully-multicoated Astro-Tech AT80EDRF converts the 560mm focal length f/7 Astro-Tech AT80ED refractor into a 448mm f/5.6 system.
– AT102ED .8x Reducer/Flattener: The dedicated fully-multicoated Astro-Tech AT102EDRF converts the 713mm focal length f/7 Astro-Tech AT102ED refractor into a 571mm f/5.6 system.
– AT102EDL .8x Reducer/Flattener: The fully-multicoated Astro-Tech AT102EDLRF reducer/flattener converts the 714mm focal length f/7 Astro-Tech AT102EDL refractor into a 571mm f/5.6 system.
– AT125EDL .8x Reducer/Flattener: The fully-multicoated Astro-Tech #AT125EDLRF reducer/flattener converts the 975mm focal length f/7.8 Astro-Tech AT125EDL refractor into a 780mm f/6.2 system.
