Default NGC 3077 a train wreck of a galaxy

Again, moonlight thwarted what I really wanted to do with this object. It has lots of outlying star clusters forming from gas and dust ripped from this galaxy in its collision with M81 and M82. I wonder if it was a spiral before the collision based on all the dust lanes still remaining.

I have picked up some of the clusters but little of their connection to the galaxy as moonlight drown that out. Another project for next spring assuming it is better than this one. The second image shows some of the outlying star clusters I've been able to identify. It is a 2x blowup of part of the main image. Those that are along an arc are sometimes known as "The Garland" per NED. I'd never heard of it before. The shot is rather noisy due to moonlight and lack of exposure time. Weather just wasn't cooperative and hasn't been since early September. But seeing was far better than usual so I took what the weather gave me. I wanted to do two more rounds but the moon was too high that night and getting higher so I quit. Never had seeing to allow another try.

Hey, thanks. I only had the DSS black and white version for this object until now. Bravo too. Very nice.

The less compressed version shows the cluster trail rather well. Thanks for this series of interacting or irregular galaxies you have been presenting.
