HOTECH - SCA Field Flattener for refractorsThis product is highly recommended
Code: SCA-FFT58
Self centring 2-inch Field Flattener with T-thread for refractors f/5 to f/8


Fully multi-coated two element lens accomodates f/5 to f/8 refractors to yield sharper, brighter images across the entire field of view. The SCA T-adaptor centre loads your camera by forcing built in rubber compression rings outward radially.

The SCA design brings your camera to the closest optical axis in the drawtube / visual back for best imaging results.
Further, its patented design negates unstable locking with thumbscrews or unified compression ring thus elliminating drawtube / visual back slop while also helping dampen vibrations.

Optimal spacing is 55mm from the CCD which can be attained if necessary using a comination of our highly populer ProStar T-thread spacers.
