Butterfly galaxies

The central pair of galaxies are Arp 270 or ngc 3395-96 in Leo Minor, and off to the left (east) are ngc3430 and 3424.
Halton Arp (maverick astrophysicist) compiled a list of interacting galaxies which include tidal interactions between comparatively nearby galaxies and presumably very distant quasars. These distances are deduced from red shifts, and Arp questioned that the red shift was always an indicator of distance.
This small scale pic is from 4x4minute subs and rhe 350D was set for fairly small JPEGs instead of RAW.
(I have senior moments in the cold and dark!)
