      Description

      First attempt at a mosaic, as a result some mistakes were made.  The more significant was using a misreported camera angle during a plate solve (long story).  Fortunately it was only a few degrees so not too much of a crop was needed.  On plus side, it was shot from a relatively dark site which made processing fairly easy. Mosaic was accomplished in APP, and normal post processing in PI, with a short stop in PS and LR.  Star reduction was done to highlight dust and quite frankly, my stars were not all that good.
