Steve, great work with the maps and overlay. I used them to help locate what I think might be the object in SIMBAD's database, the planetary nebula G321.3-00.3 at coordinates 15 17 31, -57 51 10.
Using a program I have, the distance from beta to gamma Cir is 55' and from beta to PN is 57' (almost the same), the three form a spherical angle of 125 degrees. This compares fairly well with the distances and angle between the three on your photo Shane. Also, the PN is 29 minutes from Lynga 3, which is 30' from beta Cir.
Unfortunately I can't find anything much about the PN itself. One source gives its dimensions as 112"x97" but it looks bigger than that in your photo. Maybe someone else knows more about it e.g. visual magnitude.

Regards, Rob.
