NGC 2437 is an open cluster in the Southern constellation of Puppis It’s thought to be about 300 million years old. Charles Messier discovered it in 1771, and it contains an estimated 500 stars with a total mass of 453 solar masses.

To investigate and comprehend NGC 2437’s relationships between colours, brightness, and the age and chemical composition of the cluster, I collected approximately 15 images with 3 pictures taken 5 times with 1.0 hour between each in the B, V, R filters, with exposure times of 50s, 35s, and 20s respectively via the Skynet robotic telescope network. The images were then analyzed using Afterglow and Cluster Pro Plus to determine basic parameters such as distance, proper motion, and size.

Conclusion:

Studying NGC 2437 was a rewarding experience that provided me with useful knowledge to study about the properties and formation of open clusters. It was also interesting to find out that the cluster is detached from the surrounding field, but its stars are not very concentrated toward the center.
