10 Hours of Carina!
Experimenting with combining RGB, hydrogen alpha and UHC filter data on the Carina nebula, this has approx 10 hours of data in it, RGB data from Hawker, Ha mostly from Adelaide, UHC from Hawker. I used Astro Pixel Processor to extract OIII from the UHC data which was used to add to the blue of the RGB, the Ha was used as luminance. Final tweaking in Photoshop. Mostly 10 minute exposures, D810A, APT camera control software, 600mm VR lens at f/4, Celestron CGEM II EQ mount, PHD2 guiding, Astronomik 12nm HA and UHC filters. I like the blue in this but the centre of the nebula has been blown out...
