The Weizmann Fast Astronomical Survey Telescope (W-FAST)

The Weizmann Fast Astronomical Survey Telescope (W-FAST; PI: Eran Ofek) is a system of two 57-cm Schmidt telescopes. The first telescope is constructed and being commissioned in Mizpe-Ramon, Israel.

The Telescopes were designed and built in the Weizmann Institute. The telescope design provides a 23 deg2 corrected field of view on a 9x9 cm in the focal plane. Our first generation camera will have a 7.5 deg2 field of view and is capable of taking 100 images per second with low read noise.

Aperture 57 cm
Focal length 108 cm
Focal ratio


Location Mizpe-Ramon, Israel
1st gen camera FOV 7.5 deg2
Pixel scale 2.3"
