This is the Soap Bubble Nebula processed as HOO. It was a very challenging target to acquire because it is exceedingly faint. It did not show in any of my subs so I had to batch process a chunk of them, just to see if I had it in the field. Every reference I checked had the same coordinates listed as the same which were not correct for me.
We've had a really good run of clear weather here. I was able to capture everything in a week's time.
