Hi all.
This is a remastered version of an old image.
I restarted from scracth, trying to bring out the best detail and contrast I can!
Long tidal tails are better visible now, and a diffuse halo around the group as well.
Interesting indeed an heavily stretched version, visible [here](, where the stellar streams are more apparent.
Hope you like it.
