Here is a rework of old data for GUM 15. This emission nebula does not have a common name, so I have dubbed it the “Southern Heart Nebula.” To me, it seems a lot more anatomically correct than the Heart Nebula in Cassiopeia.

Tech Notes:
ASA Newtonian, 500 mm aperture, 1900mm focal length, F3.6
FLI Proline 16803, 9 mm pixel, 4096 X 4096
ASA DDM85 equatorial mount
