Description

First serious light on the cem70 and 8" EdgeHD!! First test of a newly-installed ZWO EAF. 

4 hours of 5 minute subs at dual narrowband. Still need to work out the kinks on guiding to get better stars, but I'm happy with this start!

Version A used black body & extinction to calibrate star colors, which really isn't correct for narrowband data. 

Version B uses RGB star color calibration in Astro Pixel Processor instead of adaptive black body & extinction, which isn't well-suited to narrowband.
