      Description

      The Hubble's Variable Nebula (NGC 2261) is a reflection nebula located in the constellation Monoceros. It is famous for its unique feature of changing shape and brightness over time, which is relatively rare among nebulae. The nebula is illuminated by a young star, R Monocerotis, whose surrounding protoplanetary disk of dust and gas causes the observed variations. Studying Hubble's Variable Nebula provides astronomers with valuable insights into star formation and the evolution of protoplanetary disks.

      This captivating image of NGC 2261 was captured using a 0.5-meter CDK20 telescope with LRGB filters. With a total exposure time of 6.9 hours, the resulting photograph reveals the intricate details of the reflection nebula. The image showcases the beautiful interaction between the light from the young star R Monocerotis and the surrounding dust and gas, which create an ever-changing appearance. This stunning representation of the celestial phenomenon is a testament to the beauty and mystery of the cosmos.
