Here are some facts from Wikipedia:

This is M33, the Triangulum Galaxy, named for its location in the constellation Triangulum. This is the third largest galaxy in our Local Group following the Milky Way and Andromeda. From a suitably dark location it is one of the most distant objects that can be viewed with the naked eye. This is absolutely not possible from my suburban backyard, but thanks to the technology of the CCD I can at least image it.

Going back in history it is first mentioned in literature by Giovanni Battista Hodierna in 1654 as a cloud-like comet. Charles Messier first viewed in on Aug 25-26, 1764. Several of the H-II regions of this galaxy are quite prominent and are listed in both my annotated version as well as by AstroBin.

Here are some of its properties. It is likely comprised by 40 billion stars compared with the Milky Way's 400 billion and 1 trillion in Andromeda. The distance is estimated to be from 2.38 - 3.07 Mly, most estimates lying in the middle of this range. The galaxy is a weakly barred spiral. One of the interesting facts is that it does not appear to have a central massive black hole.

I am mostly satisfied with the acquisition frames of this galaxy. Previous experience with it has taught me to concentrate on more integration time as it is surprisingly faint for such a close neighbor. By doing so I may have captured the faint cloud surrounding this galaxy in between and beyond the main structure spiral arms.

I am least satisfied with the color processing. One, I have a tendency to over process in LRGB, something I will endeavor to correct perhaps in a later revision. Two, my ES127 still shows signs of blue bloat. The stars, particularly the blue ones, appear too blue and smeared out. When I calculated stats on the final linear integrated frames for each channel, the blue channel showed noticeably higher FWHM for the stars. Additionally, the eccentricity of many of the stars was significant. This has been a noted issue with my equipment that could be due to telescope, CCD or both. It is my hope to address this issue soon after receiving a new camera and adjusting the tip tilt of the refractor. This latter adjustment may not be necessary, but I hold it as a telescope condition that needs to be checked.

Thank you for viewing the image.
