I was not going to post this image, but it turned out better than I expected.

My original plan for the night consisted of just shooting a bit of H-alpha to test my battery and camera cooler on a different location. I decided to capture 2 subs each of OIII and SII at the end of the session, just to see how easy this emission nebula was going to show up in the other 2 filters. And well, it's definitely bright!

This image uses tonemapped versions of the Ha, OIII and SII channels for color, and pure Ha as luminance (no noise reduction). Version B shows the entire field of view, version C has the 3 different channels with an auto stretch applied.
