Another night with shifting clouds, but with the combination of a 14" aperture and dual narrow-band filter, I was able to punch through the mist. This is just an extension of my EAA work, so pretty happy to produce something that looks a tad like real AP! This 5 min live stack pulls out a surprising amount of detail in this cosmic lagoon. Indeed, I first thought that the concentric rings of nebula and central channel were artifacts - however, the expanding shells around NGC 6530 and the central lane are well documented in the literature. Thrilling to be able to see this detail in a 5 minute capture.

The original EAA live stack and comments can be seen here.
