Description

Shot this for the Sky Watcher Target of the Month submission. This is probably the faintest object I've tried to image and, at only 10 hours, it would benefit by considerably more time.

I tried something different (for me) and tried to match the wavelength of Ha and OIII to the hue values from an online calculator. I then used the hue values in the NarrowBandColourMapper script in Pixinsight. So, it looks a little greener than I'm used to.
