This is my final experiment combining DSLR RGB data with HDR luminance from a cooled CMOS camera. In this case the RGB was collected two years ago using a Canon 70D (unmodified) mounted on a 6"RC, and the luminance data was recently collected with an ZWO ASI1600MM Pro mounted on an 8" Newtonian. Once again, the luminance layer brings remarkable clarity to the original RGB image. I believe that the detail of this image can be further improved with more and better luminance data. I collected 6 hours of luminance for this experiment, but only used the best 2 hours based on FWHM and star count. The seeing was very uneven.
