M37 Open Cluster

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.

M36 Open Cluster

Messier 36 is an open cluster located in constellation Auriga, not far from the bright star Capella. The cluster is approximately 4000 light-years from Earth and it has diameter 14 light-years. There are another two open clusters in the vicinity. Specifically it is M38 (north-west) and M37 (south-east).

The picture is a stack of 50 images, each has 60 s exposure time, which means less than hour of the integration time. Another Messier object was captures. I hope, I will finish the whole Messier catalogue this year.

M38 Open Cluster

Messier 38 is an open cluster located in constellation Auriga. It has diameter 25 light-years and it’s approximately 3500 light-year away from Earth.

I managed to capture two open clusters this night already (M39 and M34) and there is still one to go (M35). Therefore I didn’t dedicate a lot of time on M38 – this means that the picture is an integration of one hour of exposure time.
