Hotech - 2" SCA Field Flattener

Hotech 2" SCA Field Flattener

Hotech is pleased to announce the 2" SCA Field Flattener. A fully multi-coated 2 element lens with very efficient light transmission while maintaining the optical quality of your telescope. It is compatible with telescopes of f/5-f/8 ratios and provides excellent, sharp, and high resolution images even when the field is expanded. 

The Hotech 2" SCA Field flattener serves as a great item for astrophotography. When using a CCD camera, stable positioning is absolutely crucial for accurate and satisfying images. This SCA Field flattener with a t-adapter mounts the camera with compression rubber rings which accurately mount the CCD to the visual back for correct installation of the CCD. 

Visual backs can only accept certain eyepiece barrel sizes, so it can be tough to understand the compatibility between these items. However, with the Hotech 2" SCA Field Flattener, this problem is diminished because the gap that would normally be between the visual back and the eyepiece is vacant with the rubber rings expanding along the flattener. Hotech has now ensured that your camera is firmly placed in the visual back every time you insert it. 

During a windy environment, Hotech short profile design stabilizes the camera from low freuqncy oscillation. The 2" SCA Field Flattener T-Adapter is 0.75" to 1.25" measuring from the T-Thread bottom.
