I originally wanted to try to get a photo of the Homunculus Nebula, but it was way too bright. Since everything was set up and calibrated, I moved the Eta Carinae out of frame and found a little star cluster to center on (Trumpler 14).
To see all the little dust pillars, bok globules, and two items on my todo list, the Keyhole Nebula and the Finger of God. I didn't even know they were in the photo until I started processing the data yesterday.
I'm also quite happy to see there are three distinct colours, as I was expecting mainly hydrogen-alpha when I started imaging.
