Dragons Remix 3!
Okay, final experiment with channels (for now!) This one used the RGB unfiltered data for colour, but I made a grayscale luminance channel from the UHC data which has the effect of reducing the star size and increasing the nebulosity a bit, but over a broader range than the Ha data and with larger stars than the Ha as luminance but smaller than the RGB mixes. What do you think?
Nikon D810A, mostly 10 minute exposures, 600mm f/4 VR, Astronomik UHC filter, Celestron CGEM II EQ mount, ZWO guide camera, PHD2 guide software, Astrophotography Tool camera control, ASTAP plate solving, Astro Pixel Processor for stacking and registration, files combined and edited in Photoshop.
