General Description

Star formation at low metallicity: the morphology of young stellar objects
 in the SMC
=====================================================================================

Simple imaging of compact red sources from the Spitzer survey (S3MC). The aim is
 to improve upon the spatial resolution of Spitzer, and see whether the VISIR images
 reveal structure on a scale of 0.3-2 arcsec, and to obtain a photometric measurement
 in between the Spitzer 8 and 24 micron photometry.

The findercharts are Spitzer 8 micron images: target is always the bright source
 in the centre of the finderchart (marked with a  circle) and even brighter in the
 PAH2 filter (11.25 micron; 50 mJy or more).

No special calibrations are required (we calibrate the photometry against the standard
 calibration plan measurement).

Priorities are based upon target selection for other observing runs.

Guide stars are chosen following the guidelines of GuideCam.
