Leserbilder Astronomie: Comet C/2013 US10 Catalina and NGC 7793
© José J. Chambó
Comet C/2013 US10 (Catalina) imaged on June 24, 2015 placed to an angular distance of 28' from the spiral barred galaxy NGC 7793 and on a background with tens of tiny galaxies in the constellation of Aquarius. Unlike which I took two days ago, in this I could take the necessary shots for compose a color image. Aside from a esthetic improvement, in this version highlights a coma with strong greenish tone, as well as a halo of same color that extends until a diameter of 6'. Comet C/2013 US10 (Catalina), that is here around 10.5 magnitude and shows a short dust tail, will increase its brightness until reach magnitude 6 at the beginning of 2016.
