We are both in the same general region.
I think RCW 91B is too close to beta Cir. If you look at Shane's photo, the object is slightly further from beta than beta is from gamma.

In hindsight, the PNe is probably a better fit for position, but I don't think it otherwise fits. We are talking about a very faint PNe but the faintest stars in the image seem about 13th magnitude. Most importantly, the size seems wrong. From the image it seems this "mystery" thing is about 12-odd arc-mins diameter which fits better with the nebula. The PNe in question is about 2-odd arc-mins diameter.
From the original photo and the surrounding star pattern I'd say the position for the "mystery object" is about RA 15 17 20.7 and Dec -57 43 59.
Probably the best bet of all is an internal reflection from either Alpha or Beta Centauri.
Has someone been back and imaged the field??
Intrigued!
Best,
