Description

NGC 1769 region in Ha/Oiii with EdgeHD11 at f/7 oag guided by MetaGuide at 0.4" per pixel. 14x5m Ha and 13x5m Oiii. FWHM in stacks approx. 1.8"

The colors are based on mapping the Ha to Ha/Hb ratio of 0.3, and Oiii to a perceptual mix of blue and green. To prevent the green from overpowering, the Oiii channel was scaled down by a factor of 0.5x. Then levels applied in photoshop and no other processing.
