APLANISSEUR DE CHAMP 2" POUR RÉFRACTEURS / 2" FLATTENER FOR REFRACTORS

The Astro-Tech field flattener reduces the normal field curvature inherent in all refractors to provide you with images that are sharply focused out to the very corners of your 35mm or large format CCD imager frame. Stars look sharp and point-like all the way across the field. You don't have to worry about photos that are sharp in the center but out of focus at the edges.
The Astro-Tech 2" field flattener has been designed to optimize the flat-field imaging performance of Astro-Tech and TMB apochromatic refractors, even the very fast f/5.5 focal ratio TMB-92. However, the field flattener will also work well with any other brand and type of f/6 to f/8 focal ratio refractor, and can even improve the imaging performance of refractors with focal ratios somewhat outside these limits.

Designed to work purely as a field flattener, and not simultaneously as a focal reducer or telecompressor, the 2" Astro-Tech zero-power field flattener does not change the focal length or focal ratio of your telescope.

2" nosepiece, with T-Thread on other end.
