Arp 85 • M51 • NGC 5104 + 5194
Arp 85 corresponds to NGC 5104, an interacting galaxy system showing tidal distortions and disrupted outer structure.
Challenge: The matter bridge between the galaxies and the disturbance of NGC 5195.
It is an LRGB image using Continuum Subtraction, where the red channel of Ha is subtracted. In the result, you can see the blobs and bubbles where Ha is located. In galaxies, it is found in concentrated regions where stars are formed.
