Description

This is a test of a different way of taking RAW frames than I have in the past.  I used a CLS-CCD filter and the histogram on BackyardEOS to set exposure time, which ended up being 60 seconds at ISO800.  This image contains 158 frames.  It looks like a good way to set the exposure time.  I processed in DSS without calibration frames, PixInsight for histogram  and curves, then Photoshop to touch up colors.  Lastly, Topaz AI to clear up any remaining noise.
