Messier 37 is the largest and the brightest open cluster in constellation Auriga. Visually, it has two deep space neighboring open clusters M36 and M38. The cluster was discovered by Giovani Battista Hodierna in 1654 and catalogued by Charles Messier in 1764. The cluster contains a lot of red giant stars and it is approximately 4500 light-year away from Earth.

This is the second deep space object, which I captured in a single night. The clouds rolled in, therefore I was able to capture only 30 pictures, 60 second each.
