NICMOS observations made in parallel with the other HST instruments have produced an archive of over 2,000 images, covering a wide range of Galactic latitudes. The images obtained through the end of 1997 were taken with all three cameras, using the JHK-analog filter grisms. The maximum sensitivity of these images is approximately 0.1 micro-Jy, which should allow the detection of such astrophysically interesting sources as brown dwarfs in the solar neighborhood and star-forming galaxies out to z ~ 3. Using model and actual spectra, we have derived the colors of a variety of objects including stars, brown dwarfs, and high-redshift galaxies in the JHK-analog filters. We have also developed software designed to perform batch photometry on NICMOS images and measure the associated object colors. Follow-up optical and infrared spectroscopy of interesting sources can be obtained with 10-meter class telescopes such as the VLT. In this contribution we describe the NICMOS parallel images and our analysis software, and discuss our preliminary findings.
