Comet C/2013 X1 (PANSTARRS) imaged on July 25th, 2016, shows these days a tail formed by a narrow and very sharp long trail of dust because our planet is intersecting the orbital plane of the comet and we see its projection of dust particles from the egde which are spread at same plane. Its head highlights with a strong greenish color due to emission of C2-molecules. In this widefield image the tail is more than a degree long (two times the apparent diameter of the full moon) until is mixed into the glow of a beautiful couple of bright stars which contrasts its colors in the constellation Centaurus, at right the redish C01 with magnitude 4 and at left the bluish C02 with magnitude 5.
