Description

Here's our old friend the Elephant Trunk Nebula rendered in HOO, shot over the last few clear nights using the dual Borg 55FL setup. I have obviously imaged this object before, but I find as I review older projects that there's often much room for improvement. This effort consists of a fair amount of data, considering I am shooting at f/3.6 and using 3nm filters.
