Tried stacking photos of the Milky Way from my backyard in Phoenix last week
I live in Phoenix, so light pollution is a nightmare for astrophotography. Last week I decided to finally try stacking some shots of the Milky Way using free software I found online. I took about 40 raw images with my old DSLR on a cheap tripod, each one at 15 seconds exposure. The stacking process took forever on my laptop, like over an hour just running the alignment. The final result actually turned out way better than I expected, with some faint dust lanes showing up. But I'm getting a lot of weird color halos around bright stars in the final image. Has anyone else dealt with this kind of color fringing after stacking, and is there a trick to fix it in the software settings?
