Description
Revision: E
Title Drizzle 2x Version, back to single camera
Description The first version was way over sharpened when developing the luminance channel, and the combined mono and OSC data was over saturated. Trying to fix those faults by going back, starting with Drizzle 2x data and only processing the mono images and paying careful attention to the sharpening particularly with BXT. Even then, I had to "rescue" some of the stars just outside the edge of the galaxy which were problematic with surrounding dark halos.
