This is a very hard image to get in southern skies because this objects stays always a few degrees from the horizon on my observation site. It was necessary more than one night and I guess that would need much more to produce a better work with some IFN data.

Even so, I liked so much this image cause it was made with a 80mm refractor and has very small tiny galaxies into the field and the principal objects from Deer Lick group and Stephan's Quintet.

I hope you like it!
