Cat's Eye Nebula
This is a very challenging target that I will definitely be revisiting at some point. What makes it challenging is the core of this planetary is extremely bright compared to the outer shell and it's quite difficult to keep the details in the core. I ended up with 9 hours 42 minutes of data with a filter and 2 hours 51 minutes of RGB data, the latter being used for true star colours.
