Messier 51 and it's smaller companion galaxy NGC 5195, a pair of interacting galaxies (designated Arp 85), are found in the constellation Canes Venatici. NGC 5195 exhibits tidal trails (stars accelerated into highly eccentric orbits) as a result of this encounter. Total exposure time was 12 hrs 20 min taken over 5 nights (74 x 10 min lights; 15 darks; 64 flats; 64 bias). Image acquisition MaxIm DL; Calibration, registration, integration, and processing in PixInsight 1.8.2 with final adjustments in Adobe Photoshop CC.
