·       Flat frame – 1,000 frames at 7fps using Aurora flat-field light panel

·       PIPP for initial crop and flat frame calibration for each movie joined to create a single movie of highest quality 5,000 frames from total of 126,232 frames.

·       RegiStax6.0 for alignment and stacking of 3,000 highest quality frames applying 0.5 drizzle factors to create a single image.
