✦ Synopsis

The high sensitivity of large format InSb arrays can be used to obtain deep images of the sky at 3-5 pm. In this spectral range cool or highly redshifted objects (e.g. brown dwarfs' and protogalaxies) which are not visible at shorter wavelengths may be observed. Sensitivity at these wavelengths in ground-based observations is severely limited by the thermal flux from the telescope and from the earth's atmosphere.

The near infrared camera (NIRC) was used for a science demonstration run on the Keck telescope during 16-24 March 1993. The camera used a 256 x 256 InSb array manufactured by Santa Barbara Research Corporation. Observations were obtained using narrowband and broad band filters horn 1 to 2.4 microns,
