The FSQ telescope at Moore Observatory provides a very wide field with a high quality CCD camera and a variety of filters. It permits photometry of bright stars, monitoring of asteroids, imaging of comets and nebulae, and narrow spectral band imaging by filter changes.
Optical System
The FSQ-106ED uses two ED (extra-low dispersion) glass elements based on the classic two-doublet Petzval design. It provides very low levels of aberration and image sizes less than a single pixel of the CCD camera which is used with it:
Aperture: 4.2" or 106 mm
Focal ratio: f/5
Focal length: 530 mm
Focal plane scale: 0.108 degrees/mm or 389 "/mm
