Hi all,
Here's a close-up image of the Keyhole Nebula. While the image could be made to look much prettier these shade of colors seem to reveal the most detail.
There are some interesting objects to note in this image, including the pale greenish stingray shaped coloration just left of the bright star Eta Carina. Notice the bright red vein like tendrils of nebula that weave about the dark keyhole. At the lower left of the image a star appears to be diffused by a circular whitish disc shaped nebula. All kewl stuff eh?
There's a better resolution of the image here
