ROSS optical camera

The CCD on the image plane is an Apogee Alta 1024x1024 pixels. The pixel scale is 0.575 arcsec/pix for a total field of view of about 10x10 arcmin.

The ROSS camera hosts 3 filter up to the 1 micron of the dichroic cut and one Amici prism for slitless spectroscopy.
For the moment being the Amici spectroscopy is not offered to general users.
