  Simple imaging program consisting of broad band mosaics of two dark
nebulae. Seeing constraint slightly relaxed with respect to phase 1
specifications. 

  The goal is to measure extinction towards background stars as well as
to measure diffuse emission from the cloud itself. For this reason, 
measuring the sky at an offset position is important.

  Generic offset template used as a precisely determined patch of sky is
needed for sky subtraction; AutoJitterOffset would not allow this. 

  Acquisition parameters may lead to too long acquisition exposures and
may be reduced, although they may be needed when sampling the most
opaque parts of the nebulosity.

  No special calibration needs, and no time constraints.
