The galaxies of the Leo-Triplett (M65, M66 and NGC 3628) are shaped by intense gravitational forces. Particularly NGC 3628 is heavily warped and sports a very long tidal stream.
In this image it is only hinted at; it had to be truncated in favour of the composition with M 65 and M 66. I hope to capture the whole almost 300,000 lightyears long tidal stream together with its dwarf galaxies in the future.
