Description

Super interesting region, I wish my FOV was large enough to get the Ha regions nearby.  While attempting to stack this image I found that using Generalized Extreme Studentized Deviate pixel rejection would cause the integration to drag on and on. The last time I tried stacking a few thousand images with GESD it took more than 24 hours.  I changed back to Winsorized Sigma Clipping and all of WBPP and integration took less than 3 hours including drizzling.  If anyone has a case for using GESD rather than WSC I'd love to hear it, if it generates a much better result then maybe I'll get to the bottom of the issue.
