Description

M51, the Whirlpool Galaxy. Just another one of those 'must capture' every year during galaxy season. M51 is also located in the Canes Vanetici and is apart of the M51 group that includes the Sunflower Galaxy. M51 is an excellent beginner target as the spiral arms are readily apparent in small telescopes.
