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 that which I took two days ago, in this I could take the necessary shots to compose a colour image. Aside from an aesthetic improvement, in this version highlights a coma with strong greenish tone, as well as a halo of same colour 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.
