A mosaic of 256x256 images from the 90-inch of the Galactic Center.

The 256x256 camera has been in operation at the 90-inch and 61-inch since 1991. It uses a NICMOS array that was built as part of the development of the NICMOS instrument for HST. NSF has also provided substantial support for the instrument. If you are interested in using the camera, please contact either Marcia Rieke (mrieke@as.arizona.edu ) or George Rieke (grieke@as.arizona.edu).
