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, […]
