I think that the degree of resolution shown of this galaxy is fantastic.....really excellent work, Leonardo!!
The stars in this galaxy are stretched out, well beyond its ordinary boundaries, as can sometimes be tentatively seen in many amateur images.
Another good image of this tidal material is at:
http://www.caelumobservatory.com
(first click on "Apogee CCD image gallery" , and then move several pages forward).
This image, by Adam Block and Tim Puckett, shows the overall structure of the tidal material very well, because it covers a lot more sky.
To be honest, I am not sure if the
narrowness of the tidal stream as seen in Adam Block's image is real......it does not look so narrow in other images I have seen.
