NGC 5316 is an open cluster of intermediate age in the southern constellation Centaurus. Discovered by James Dunlop in 1862, it is approximately ~4000 light years away from Earth, in the Carina-Saggitarius arm. The estimated age of NGC 5316 varies quite greatly, the lowest of 51 myr. measured in 1968, while the highest was measured […]
Read more "NGC 5316"Introduction NGC4609, alternatively recognized as Caldwell 98, is a young open cluster within the southern constellation of Crux – a cross-shaped asterism often referred to as the Southern Cross. A fascinating fact about the Crux constellation is that it is widely used as a national and distinctive symbol in many countries (Wikipedia contributors, 2024). Figure […]
Read more "NGC 4609 | An Open Cluster in Crux"NGC 2439 is a young, open cluster of 824 stars in the Southern constellation Puppis. It was catalogued by Per Collinder in 1931 and has unusually low extinction leading some to argue that the cluster doesn’t exist at all Kaltcheva 2001. In order to study NGC 2439 I collected 15 images using the Prompt6 telescope, […]

It was first discovered by Scottish astronomer James Dunlop in 1826 and is estimated to be over 1.2 billion years old. Interestingly, the NGC 3680 star cluster was classified as containing less than 50 stars, yet the number of stars making […]

This cluster was also independently discovered later, which caused some discrepancy on whether or not IC 2395 and BH 47 are the same cluster, but both Claria´ et al. (2003) and […]

It was discovered in 1772 by Charles Messier, but its sighting was also recorded before 1711 by G.D. Cassini. As it was often described as having a “heart-shaped figure“, NGC 2323 earned itself the nickname of Heart-Shaped […]
Read more "NGC 2323 Cluster Analysis"NGC 2270 is an intermediate aged open cluster, located in constellation Monoceros very close to the celestial equator, making it partially visible in both equators at certain times of the year. A fairly large telescope is needed to observe this cluster considering its size, brightness, and classification. The cluster was determined to be approximately 1.1 […]

It is located in the constellation Carina approximately 405 parsecs from Earth (Robichon et al., 2005). It is classified as an intermediate age cluster with an age of 300 Myr (Fritzewski et al., 2021). Concerning its history […]
