sh 88b is a compact hii region composed of a cometary nebula, sh 88b1 and of an ultracompact hii region, sh 88b2. both components are embedded in a dense molecular core and are not optically visible. sh 88b2 lies in the very centre of this molecular cloud. in order to study this high mass star forming region, we observed it in the near ir (j, h, k) with the camera monica mounted at the cfht (collaboration with d. nadeau). the exciting star of the sh 88b1 region has been identified. the visual extinction of many stars in the associated stellar cluster has been obtained. it increases very quickly, from about 10 to 40 mag in less than 10 arcsec, at the edge of the molecular core. the exciting star of sh 88b2 is not detected in k, which indicates an extinction larger than 70 mag in the direction of the cloud.s core.

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
