NGC3432

NGC3432

A quite stunning and rather interesting lesser known edge-on spiral galaxy in Leo Minor. NGC 3432 or Arp 206 was catalogued by Halton Arp as a galaxy with "material ejected from the nuclei." There are certainly many granular like structures visible in my sketch. The disruption to the structure is caused by the powerful gravitational interaction with another fainter mag 15.3 UGC 5983, dwarf galaxy to the southwest of NGC 3432. It is just visible in the sketch to the lower right. North is up. Sketch made using the 505mm Newtonian & Watec 120N+ video camera on Feb 24th 2011
