M81 and M82 Space Walk Among the Stars

Charts to accompany the MP3 guide.

M81 and M82 Chart

Chart adapted from Cartes du Ciel.



Image 1: North is to the right, West is down. M81 (left) and M82 (right). The image is approximately 1 degree wide. (The thin dark lines across M81 and M82 are artifacts of stitching the SDSS images together. That faint blue cloud above M81 is irregular galaxy Holmberg IX, UGC 5336, at 14.8 magnitude.)

Image 2: North is to the right, West is down. The route from M81 to NGC 3077, with a stop to look at Struve 1387. Note the location of the two faint stars referenced in the MP3 guide. They may appear to be outside the glow of the galaxy in your telescope. The supernova of 1993 was very close to them. Images pick up much more of the faint spiral structure than you can see in the telescope. (The thin dark line across M81 is an artifact of stitching the SDSS images together.)

Image 3: North is to the right, West is down. The route from M81 to NGC 2976. (The tiny galaxy above left center is UGC 5302, 14.5 magnitude. The round galaxy at bottom center is NGC 2959, 13.0 magnitude, which I've been able to see in my 4.5-inch reflector. Remarkably, the tiny edge-on galaxy just above and right of it is also in the NGC catalog- NGC 2961, at 14.9 magnitude! The thin edge-on further to the right is UGC 5210, 15.7 magnitude.)
