Summed J+H+K image of the Hubble Deep Field

This is a sum of roughly 44 hours of infrared data on the Hubble Deep Field, obtained with the IRIM infrared camera at the KPNO 4m Telescope. Here, the J, H and K images have been coadded in order to maximize depth and the number of detected sources. The images in the three separate bandpasses each reach roughly comparable depths, detecting most objects with similar signal-to-noise.

IRIM was rotated to an x-axis position angle of 67 degrees for the observations. Therefore, the orientation of this image matches that of the HST WFPC2 data, with NNW up and ENE left.
