This interesting group (also known as the
Pisces Galaxy Trio) is located at distance of about 100 million light-years
(NGC 467 on the right even 250 MLY).
The largest galaxy
(diameter more than 200 kLY, to the left) is a classic shell
galaxy interacting with smaller neighbor blue spiral
Surprisingly the third galaxy
also shows some hints of shells.
In the background we
can also find some much more distant galaxies, already the
little face-on spiral near the left edge (PGC 1252050) is
situated some billion light-years from Earth.
Total exposure time (with 8" f/4 Newton): 16 hours
Dimension: 6.1' x 5'
Surface brightness: 15.5
