I shot this image a few years ago. I do things differently now, but I still like the look of this one. As for M33: if you are on Astrobin, you already know all about M33 being the smallest spiral in our local group of galaxies; being the farthest object we can see (barely) with the naked eye; and being alternatively referred to as The Triangulum Galaxy, and also as The Pinwheel Galaxy (as are several other galaxies), so I’ll spare you all of that.
