Scientific paper

The CIRCUS IR camera is based on a 32 x 32 InSb CID that is cooled to liquid He temperatures to reduce dark current. The camera is equipped with the J, H, K, L, and M filters. After presenting design and performance data for the CIRCUS camera, attention is given to the results it has obtained for the nuclear region of nearby spiral galaxies and interacting galaxies, as well as to the successful observation of extended large aromatic molecule features at 3.3 microns in the edge-on galaxy NGC 891. Further from the Galaxy, a direct image has been obtained of the 'double quasar' Q 0957+561 together with the lens galaxy responsible for the gravitational mirage.
