This image shows you a deep sky object bathed around 6 degrees west from beta Draconis, forming a head of Draco.
Arp330 has 5 or 6 tiny galaxies with 15th to 18th magnitude brightness paralleling like a chain.
Of course this object is out of list for observing with amateur telescopes.
The brightest galaxy in center of MCG +9-27-94 has a visual brightness of at most 15th magnitude and only 0.3 arc minutes in diameter.
Member galaxies of Arp330 have gravitational interactions each other, considered that they're forming a small scaled galaxy group.
