Description: Deep near-IR images (J,H,Ks) taken to produce high-resolution extinction maps. Regions neer dense clouds show some extended emission (cloudshine) which we believe to be Galactic starlight scattering off dust. One region, L1448, shows a number of remarkable outflows. Comments on Reduction: Cloudshine complicates data reduction. Regions covered by extended emission will be dimmer than in reality, since sky-subtraction will subtract out real signal. This process acts like a sharpening filter, enhancing contrast in these images. Telescope: Calar Alto 3.5-meter Status: Complete Sampling: Seeing during these observations was good, often 0.6-0.7 arcseconds. Areal Coverage: Each frame is 15.4 by 15.4 arcminutes. A total of seven science frames and two control fields were obtained.
