The instrument
currently in use on the 85cm telescope is:
MiCPhot - a Multicolor CCD Photometer
that
consists of
a Princeton
Instrument MicroMAX 1024BFT CCD camera
and a set of standard Johnson-Cousin-Bessel BVRI filters at the prime focus of the 85-cm
Telescope. Please refer to this paper for details.
Observers may do BVRI
sequential photometry on a fast-readout mode (short down to 1 second or
less if using Frame Transfer function. Expected objects magnitude
ranged in V=9-17 mag; FOV ~ 16' x 16' at a scale of 0.96 arcsecond per pixel.
