Description

Not many clear nights this summer, but in July there were a few nights here in New England where I captured some nice data within the Cygnus constellation.  This was one nights of capture, with ~4 hours of good darkness, I set each hour per filter with dithering every 2 frames. 

They were stacked and calibrated with DSS.  For all 3 channels:  Did a DBE, EZ Denoise (& duplicated the Ha here for the Lum), Stretched with a mask, StarNet for star removal, and channel combined using PixelMath (SHO/HSO).  The duplicated Ha Lum was Background Neutralized, and MLT, EZ soft stretched, LHT, MMT, Star reduced with MorphTrans, and LRGB combined with the PixelMath RGB image. Curves and Color saturation modified to taste with masks.  

Happy World Photo Day today (8/19)
