VIRIS: A Visual‐Infrared Imaging System for the Lick Observatory 1 Meter Telescope


We describe a system in use at the Lick Observatory 1 m Nickel telescope for near‐simultaneous imaging at optical and near‐infrared wavelengths. The combined availability of a CCD and a NICMOS3 camera makes the system well suited for photometric monitoring from 0.5 to 2.2 μm of a variety of astrophysical objects. Our science program thus far has concentrated on studying variability trends in young stellar objects.
