Description

My annual attempt at this pretty part of the sky. This time, it's with a Rokinon 135mm lens which has much less CA than my Canon. Still had some issues with stars and color fringing. Still, better than last year and processing was MUCH easier with this better data. I did have issues with blue hot pixels as the dithering didn't work for some reason and I no longer use darks. A bit of Ha was blended into the L and R channels. L 16x150s, RGB 10x150s, Ha 8x300s.
