There are only a few interacting galaxies that are readily visible through scopes. Unfortunately none are very bright, so the key to seeing much is aperture - the bigger the better.
I haven't seen this particular pair, but being in Canis Major, it is well placed for a purv this new Moon and next.
One of the brighter pairs of interacting galaxies is the pair known as the "Antennae", NGC 4038/9 in Corvus. In smaller scopes this pair has the appearance of a Pac Man figure. Larger apertures begin to show concentrations of stellar and nebulous areas and more details within each. The Antennae is a favourable position for this new Moon period early in the morning.
Another relatively bright pair is the Whirlpool Galaxy, M51. Problem for us here under southern skies is M51 is never very high in the sky.
Our own Milky Way has also undergone many, many interactions, and is still swallowing up smaller galaxies now. The Large Magellanic Cloud is thought to be in the process of being consumed, though some studies suggest the tidal influence of the MW on it is just ripping it apart. There are also several remnants of swallowed galaxies, a couple are observable but are extremely, extremely difficult to observe. One is in the constellation Sagittarius which means trying to identify what is the MW and what is the remnant galaxy.
The giant globular cluster Omega Centauri is also thought to be the remnant core of a smaller spiral galaxy swallowed up by the MW long, long ago. There are several factors that distinguish Omega Centauri from being a 'normal' globular cluster, including its massive size, variations in the age of its component stars (normal GS's stars are pretty much all the same age), and the distinct possibility of there being a black hole in its core to be able to maintain such a stable size and shape with so many stars so close together.
Mental.
