      NGC 4499 - Barred Spiral Galaxy in Centaurus

      NGC 4499 is rare target because of it's tiny size and low surface brightness - requiring large aperture and long focal length telescope to capture in decent detail. It is classified as a barred spiral galaxy (SB(rs)bc) and is located in the constellation of Centaurus. Discovered by John Herschel in June 1834, it lies approximately 193 million light‑years away and spans roughly 102,000 ly across the sky. According to A.M. Garcia, NGC 4499 is a member of the NGC 4696 group, which contains at least 79 other galaxies.


      The image was captured using Telescope Live’s 24-inch Planewave CDK telescope at their Chilean site, utilizing an LRGB filter set. Though the dataset represents a relatively modest exposure in total integration time, it successfully brings out the galaxy’s central bar, spiral structure, and faint surrounding disk against a rich stellar background. The galaxy is extremely tiny, even with almost 4 meters of focal length.
