Thor’s Helmet

“Thor’s Helmet,” aka NGC 2359. First time I ever shot this with any camera. For years I’ve passed this guy up for bigger or better objects nearby, but not on this night. It was a main goal for this night’s imaging session. It did not get high enough to image until 2:00 am here and I took a nap as soon as I started it going. Luckily, I got enough data before sunrise to make a half-decent final image

I was killing time while waiting for Thor’s Helmet to get into position, so I shot the Horsehead and Flame Nebula region.  I used Fitsworks to crop out the dithering artifacts and set a black point and do the initial color balance. Photoshop and some hue and saturation adjustments to finish it off. Then, one pass with color blotch action and one horizontal banding removal action later and this is how it came out.  A few other tweaks were done, too. Not too bad for the minimal effort and a full moon night.
