NGC 2090 is an infrequently imaged spiral galaxy located 40 million light years away in Columba.
The structure of NGC 2090 is an SC type of spiral, the arms are quite faint and required considerable integration time to properly resolve.
NGC 2090 was one of 18 galaxies that were part of the HST Extragalactic Distance Scale Key Project to better define the value of the Hubble constant. The sparse nature of the galaxy’s arms allowed The Hubble Space Telescope to resolve stars leading to a more accurate red shift calculation.
Imaged in LRGB at Observatorio El Sauce, Chile on our CDK 1000 telescope.
