NGC 6207

Observation Notes:

I had never taken the time to look for this galaxy next to M13, but it was visible without much effort through the 8-inch Dob. It shared the view with it’s huge globular cluster neighbor at low power. The 120X view offered the best view, showing the galaxy to be elongated north-northeast to south-southwest at a PA of about 20 degrees (the NGCIC project lists a PA of 15 degrees). It appeared to be about 2 arc minutes long by 1 arc minute wide and sported a what appeared to be a nearly stellar core. This ‘core’ is apparently a superimposed foreground star. To the southeast, a pair of bright stars lit the view, with the brighter southeast star burning yellow-orange.

  1. This one shows up quite nicely with a larger aperture and dark sky. Pretty little galaxy near M13.
    I didn’t know about the star at the center. Looked up a few photos and the star is directly beside the core, looks like what we see visually is a combination of the two. From comparing the red and blue DSS it looks like the star is heavy in the red/IR, so unfiltered CCD images will show the star as brighter than our eye sees.

  2. It’s funny how simple it was to spot once I actually looked for it. It will be a regular stop anytime I check out M13 now.
    While making the observation, I took for granted that I was simply seeing the core of the galaxy. Then I noticed Steve Gottlieb’s observing comments at where he suggested it was likely to be a superimposed star. And sure enough, photographs and other reports made that appear to be the case. That’s an interesting note about the reddened spectrum. I wonder how much the star contributes visually to the combined glow of the knot at the center?
    Thanks for the comment.
