There are plenty of reddish-brown stars throughout the photo, maybe its just a fluke?

* Seems that the only infra red images or part of the overall image is that of Proxima. Long exposure helped. I think the halo is due from the infra red lens.

Or maybe it's right along the galactic
disk ?

* Yes, Alpha Centauri (system) IS seen against a backdrop of stars... in a very busy area along the galactic disk not far from the Coal Sack and next to the Southern Cross (Crux).

* That's why I just had to post that stellar map to show stars on the opposite end of the pic. *g* The view wouldn't be as crowded.
