Thor's Helmet
A bit of a work-in-progress. I got RGB data on this object at new moon - 40 mins each. I've been trying for narrowband recently, with mixed results because of the heat and a moonlight gradient. But I have decent OIII - 4 hours' worth - which seems to work well as a luminance layer for the RGB.
Cheers
