Default M81 and M82 and Combo

All:

Below are photos of M81 (and Holmberg IX), M82 and a wider field showing both. Exposures for both were originally taken last year, and augmented with more exposure time, then processing, this year. Additional photo info is at:

Lightbulb M81 & M82

On your Recently Added photos page the caption for M82 reads: "The image below is of the irregular galaxy M82 (NGC3034) in Ursa Major, the field neighbor to the larger spiral galaxy M81, though four time further away from us." M81 & M82 are in fact at nearly the same distance (about 11,830,000 LY & 12,710,000 LY respectively) and are an interacting pair. M82 passed through M81 about 600,000,000 years ago. Very deep exposures show a bridge of intergalactic stars connecting the two galaxies (Sun, et al., 2005; de Mello, et al., 2008).

All:

Appreciate the time to take a look and comment on the photos. There are other galaxies in the group, but I think I'll move on to some other subjects.

Given this month's article in "Sky and Telescope" concerning radio astronomy, and the false color image showing the interactions between M81, M82, NGC3077, and NGC2976, I should have reconsidered the distance info given on the web based "Deep Sky Browser" as questionable, but then it's published,...on the web,...it must be right???
