Color created by mapping the SII, Ha and OIII data respectively to the R, G and B channels (called "Hubble" Colors). I make diffraction spikes around some stars using "StarSpikes Pro 2" plugin in Photoshop. Over 16 hours of exposure time on more than 4 different nights contributed to this final picture below. This is the first time I used QHY163M camera on my Sharpstar 107 F6.5 telescope. This camera always produces very impressive results, thanks to extremely low noise, very high quantum efficiency and precise chip-cooling control.
