NGC 6934

NGC 6934 is a globular cluster that is home a a few hundred thousand stars in the constellation of Delphinus (or dolphin). Lying 50 000 light-years from Earth, in the outer reaches of our Milky Way galaxy, NGC 6934 is home to some of the most distant stars still to be part of our galactic system — in a sense, it's a far-flung suburb to the Milky Way’s city center (source: SpaceTelescope). I had no plan to image this last Saturday but it was in a perfect location while I waited for my planned target - Andromeda. I have taken no images of clusters with my new camera so I finally figured it was about time.

I could have set up the Atlas Mount in the front lawn and moved the scope of the permanent pier to get a much longer imaging window which is what I normally do for with polar objects. However, I was very sick - I was being treated for sinusitis and had no strength or will to set up. Turns out I have pneumonia and should not have been out at all.

Anyway, here is my first image of a globular cluster. It is only one hour and I did not do any luminosity subframes. It seems some people always take luminosity data on any object others only save it for something like a galaxy or nebula, in any case I chose to not collect any. The star field came out colorful and the cluster was very small so I decided not to crop it too much and focus more on background. Lots of orange, gold, and blue stars appear in the background and there are a few large blue stars on the bottom of the image.
