Photography at 9400 Å of infrared and molecular line sources

Abstract

Photographs with an S-1 image tube at an effective wavelength of 9400 Å have been obtained for five northern infrared sources. These photographs show objects which do not appear on the Palomar Sky Survey red plates, and which in some cases agree well in position with infrared components of OMC-2, Mon R2, Sh 269, NGC 7538, and OH 0739 -14. The case of OH 0739 -14 is particularly striking. We have found a bright, barlike nebulosity which agrees in position with known infrared and molecular sources. At one end of this bar is a very red stellar object.
