TS 2" PHOTOLINE 0.8x Reducer Field Flattener for 70mm and 80mm ED Refractors from f/6 to f/8
TS 2" PHOTOLINE 0.8x reducer / flattener for for 70mm / 80mm ED Refractor Telescopes
2" Field flattener with T2 connection on the camera side - reduction of the focal length: 0.8x for smaller EDs
This 0.8x corrector is designed especially for smaller two-element ED refractors.
It is suitable for ED Refractor telescopes from 70mm to 80mm aperture - from F6 to F8
The reducer fits directly into the 2" focuser. On the camera side, there's a male T2 thread. The optimal back focus distance is 55mm. So a standard T2 ring (see accessories section) in combination with a DSLR camera gives the correct distance automatically.
Telescope facing the reducer offers a 2" filter thread (M48x0.75mm).
Fine-Tuning: with our T2 Fine-Tuning Rings and extension rings, you can make a fine Tuning to optimize the star images in the edges if you use a bigger sensor. For typical DSLR sensors, this will be not necessary.
