This image is a combination of my own H-alpha imagery together with color information from the Digitized Sky Survey made by the Palomar telescope. The Poss-2 red and blue data is used for the color generation. This shows what result is possible if you combine professional and amateur data in one image. Version 2:

By searching for some papers on the internet I was able to find databases giving the coordinates of red and yellow hypergiants, post-red hypergiants (supernova progenitors), variable stars and globular clusters in M33. With pixinsight I overlaid these …
