Description

Revised Version 1/24/2023:
This was one of the earliest images I took with the QHY268 camera.  Sorry, but this was done with my ZWO ASI071MC Pro.  I did not get a lot of subs, but here I merge 200 sec and 300 sec subs to add some data.  The addition of the 300 sec subs brings the total integration time up to 4.6 hr.  Cetainly the addition of new processing tools helps.  I also believe that I got better color on this.  I also deemphasized the stars more so than the original.  Field stars and also foreground stars within the body of M33.  I do believe that the corrected stars and the better convolution with the new tools helps bring out the finer detail and enhances the dark molecular clouds.  Also better detail in the HII regions that are a bit fainter than one typically sees with the addition of data using a narrow band filter.  I still have not used that filter and there is no red channel addition here.  So what you see is au naturale.

Original Version:
Not much to say other than this is oft photographed and presented. The benefit we have of being as close to this as we are is that we get to see a multitude of objects displayed on a single image. A scan of the SIMBAD results yields pages of objects including many supernovae remnants, star forming regions with deep Ha emissions and so on all scattered around many dark dust lanes. There are also many x-ray sources as well, suggesting numerous binaries with either black holes or neutron stars. No doubt the Milky Way looks similar to those on that side peering at us. I really like the apparent "bubbles" that seemed to be formed by the hot blue stars in some cases. In particular, isolated tight groupings of these huge behemoths. That is my interpretation...

While I collected about 90 subs on this from last week at 300 sec and 200 sec. I used only 30, 200 sec subs for this image because of issues of various kinds. So only 1.6 hrs total.

The original submission is a wider field of view and M33 is perfectly flat and upside down. I will also include an annotated version, but if the Astrobin mouse over captures everything, I will delete it. I like to see more of the smaller items that pop up and are not usually presented. As it is, PI still misses a fair amount.

The final image is flipped to upright and since I had the real estate, I put an artistic tilt to it.
