I'm quite proud of this one. GSSP turned out to be quite rainy and cloudy, so I only had one clear night to shoot. Although I normally dislike Milky Way shots I decided that given the little time I had, it would have to do. I decided to do a typical shot of the Sagittarius Region, but I decided to do it right. With me I had a f/1.2 35mm non ed lens, so I decided to use that. Instead of using its f/1.2-ness, I stopped the lens all the way down to f/8. At a dark site like GSSP, it's kinda silly to shoot with that fast a lens, and I wanted the stars sharp more than I wanted gas and dust. The Milky Way is super bright as it is.
Halfway through shooting, I decided I wanted to do a mosaic. With some quick drawings on a notepad, I figured out the orientation and placement of the Rho Oph frame, and started shooting just as some low clouds were coming in. All in all, I got nine frames on the Milky Way, and three frames on Rho Oph. Not bad, considering I was also shooting M16 that night.
I actually had to build a computer to process this picture (well I was going to anyway, but it turned out my old comp couldn't handle a 8000x6000 mosiac.) The processing was done in Pixinsight with Microsoft ICE doing the final alignment of the two frames. ICE 2.0 is awesome, and everyone should go download it. Funny enough, I did zero color calibration in Pix. With no light pollution, the colors were already correct!
