What CCD camera is best with the SC-2438?
The first consideration is the desired field of view. At prime focus of the SC-2438, using a coma corrector, the plate scale is 0.125 arc seconds per micron. If the seeing is one ar second or better, then the pixel size should be nine microns. If the seeing is two arc seconds then a camera using 18 micron pixels (or 2 x 2 binned 9 micron). The second consideration is the size of the coma corrector. The Paracorr® corrector will provide a 33 arc minute field of view. The custom corrector will provide over one degree and can accommodate a CCD chip over one inch square.
