The Whirlpool Galaxy, also known as Messier 51 (M51), is a striking galaxy located in the constellation Canes Venatici. Situated approximately 23 million light-years away, this cosmic wonder spans a staggering 80,000 light-years in diameter.
M51 is a favorite target among astrophotographers due to its iconic spiral arms, which were first discovered in 1845 by William Parsons, the 3rd Earl of Rosse. This discovery also marked the first time spiral arms were detected in any celestial object.
One of M51’s most fascinating features is the prominent hydrogen-alpha (Hα) region near the galaxy, commonly referred to as the "Hα Cliffs." Capturing this faint structure poses a significant challenge, requiring exceptional dedication and skill. To fully unveil the cliffs, our team accumulated an incredible 383 hours of Hα data, with individual exposures averaging 1,300 seconds each.
The result is a breathtaking view that highlights not only M51’s distinctive spiral structure but also the delicate, glowing Hα regions that surround it.
