The Rosette in APP HOO2 Preset
This image was taken with an Astro-physics 130GTX @ f/4.4 and a QHY268c color camera through an L-Extreme Dual Band filter in a Bortle 8-9 zone (north Seattle). About 60 exposures of 90 seconds each. This combination is great for getting good results in a light polluted sky.
I used the Extract Ha and Extract O3 algorithms and then color combined with the HOO2 preset which I loved for this object. I also used HSL to desaturate the background and saturate the main colors of the nebula. Post processing was done in Photoshop with Photoshop and Topaz Denoise.
