Very nice. The horsehead is one of my favorites. I remember being really amazed when I found out how big it really is. As a kid I imagined it being the size of a big star or so or maybe a solar system.

This is with 5hrs20mins of 10min subs stacked. Getting much cleaner and more faint, wispy details popping through.
