M 51—The Whirlpool Galaxy

M 51—The Whirlpool Galaxy

Ultra-deep view of the Whirlpool Galaxy—a collaboration project initiated by Yuri Toropin.

How deep amateurs can go? The Hubble Ultra Deep Field has inspired amateurs from the very first moment it became available. In 2010, Yuri Toropin, PhD, has started an international collaboration project whereby many amateurs worldwide have submitted their M51 imaging data into a single large dataset. This is my own version of processing this wonderful collection of photons.
