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,

Les,
I agree with you on this point and initially had this reservation about the PN. The HII region is about the right size but not exactly in the right location. The PN is in about the right location but not the right size.
The internal reflection might be the go.
Curious! If it still shows in a follow up image, it will be interesting.
Regards, Rob
