Messier 34 - Open Cluster in Perseus

Updated: Jun 1, 2023

Messier 34 is an open star cluster that is located about 1,500 light-years away in the constellation of Perseus. That makes this deep-sky object one of the closest star clusters to Earth!


Despite M34 being a large, bright object in the Messier Catalog, it is not a very popular target for beginner astrophotographers. Why is that, exactly? It may be perhaps because it is not a widely known object, and it doesn't offer much to the eye aside from sparse, beautiful blue stars. It also doesn't have a cool nickname like many other Messier objects. Take a look at other star cluster astrophotography we've captured like Messier 37 and Messier 48.

How to Locate Messier 34


M34 lies in the constellation of Perseus, not far from the Andromeda Galaxy (M31) and Triangulum Galaxy (M33).


It can be seen with binoculars and any size telescope and is pretty easy to find in the night sky. Under very dark skies, you may be able to spot this cluster with the naked eye, assuming you have good vision.

Cool Facts

  • At a distance of only 1,500 light-years away

  • One of the nearest Messier Object from Earth

  • About 200 million years old
