Thanks to Juan, Vicent et al for the new features and the opportunity to test the new version of PI.  PhotometricColorCalibration and Large-scale pixel rejection are already indispensible.

Great shot, the best I have seen of this field
if you only had a bit more field on the lower side, there are interesting structures that deserve to be in this already gorgeous image.
