Whirlpool Galaxy (M51)

I have been attempting to use my Meade LPI as an autoguider. I had limited success last night (wind was gusting between 10 and 15 MPH). I was able to capture some 1 min exposures between the gusts. I took 30 but only about 8 came out. So here's the results.





The Whirlpool Galaxy (also known as Messier 51a, M51a, or NGC 5194) is an interacting[5] grand-design[6] spiral galaxy located at a distance of approximately 23 million light-years in the constellation Canes Venatici. It is one of the most famous galaxies in the sky.[7] The galaxy and its companion (NGC 5195) are easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars.[8] The Whirlpool Galaxy is also a popular target for professional astronomers, who study it to further understanding of galaxy structure (particularly structure associated with the spiral arms) and galaxy interactions.
