M51 – the Whirlpool Galaxy. Is there a more beautiful and intriguing object in the sky? I don’t think so.

Data: L = 31 x 300s (binned 1×1); R = 25 x 100s (binned 3×3); G = 25 x 125 (binned 3×3); B = 25 x 150 (binned 3×3) – thanks to the advice given in S@N magazine March 2012 #82 & September 2011 #76.
