Update: I've added a polynomial stacking routine. Essentially a noise rejection filter. Removes satellite trails and hot pixels. Before and after shots. These are low resolution jpg normalized with gamma 2.2 to illustrate the effect. These are linear images - no post processing has been performed.

A new version. No major changes. Largely bug fixes, code tidy up and provision for setting ImageMagick in-built resources - threads and memory - on a per-session basis. Removed unnecessary parallel processing routines, letting ImageMagick handle the resources.
