Cygnus in H-alpha 48-panel mosaic

This shows the output of the APP program after the automatic mosaic process. APP finds all overlaps (i used 15% for the SGP Frame and Mosaic wizard settings) and positions and the right orientation and distortion correction! I loaded a masterdark, bad pixel map and masterflat together with all the single light frames. Each panel is a single 15 minute H-alpha (7nm) exposure with QHY16200 CCD/ Esprit 100 f5.5 refractor) Again, this Flickr upload is a downscaled version at 12.5%, the full version is 600 megapixels.

 

Still need to do registration and background optimization.
