Back to the Lagoon Nebula. From my backyard, this nebula is only visible for a couple of hours at a time. During galaxy season, the 10" is on the mount when it's really too late in the morning to go after another galaxy. But the Milky Way is coming up over the trees about 3:30 am, and there we find this! Glowing hydrogen gas provides the red color, and oxygen the blue that whitens up the nebula in the brighter lower middle. Some blue may also be light reflected from the relatively new nearby stars.
This is also my first imaging run with the Astro-Tech Coma Corrector. It's taken me a while to fit it in with the camera setup, but it appears to work beautifully.
