M33 was often shown in the astro-fora this year in very high quality. Some photographers enhanced the prominent HII-regions of the galaxy by adding narrowband-data.
OK, I had to try it too. Of course, there could have been some more OIII-frames, but the enhancement is there alright.
Here is an older image, made with the QSI.
