From Adam Block: "For me this nebula has a curious special quality. When at the telescope delivering my public observing programs at the SkyCenter I often type the catalog names of objects in the dark. The Double Cluster is a must-see gem of the winter evening sky. By catalog name one of the clusters (the brighter one) is called NGC 869. However, in the dark (and in my brain) it is easy to transpose the "69" and point the telescope at this nebula. Since the clusters and nebula are near each other in the sky it isn't obvious I have made this error until I look in the eyepiece and discover a faint misty glow instead of the blazing myriad of stars I expect. Now having captured it using a sensitive camera I can really see it for its beauty rather than a reminder an error I occasionally make."
