Description

This is a crop of the Elephant Trunk Nebula image I just posted, showing this small Oiii emitting PN also known as PM1-333. Here is a paper confirming that it is a planetary nebula: https://iopscience.iop.org/article/10.1088/0004-6256/137/5/4140

This is a RASA8 image and obviously it is a better target for a long focal length scope.

The bright yellow star up to the left is Herschel's Garnet Star (µ Cephei)
