Description

This is probably my toughest target to-date. The core is very bright and the outer nebulosity is very dim. In fact, the core is so bright that it caused diffraction spikes that were difficult to process out. I was hoping for better, but this one is what it is. This is 200x60s each for Ha and OIII for the core and 100x300s each for the outer nebulosity.
