Very useful for astronomical excursions. This App allows to look for observable asteroids, comets, planets, moons, satellites for the observation-night. Nice are the checklists for Messier, Herschel400 and Caldwell-Objects.
But a tiny error: the coordinates of Ceres are different if you to look them as a dwarf planet or as an asteroid. The error was today about 2 minutes in RA and 14 minutes (!!) in Deklination. Too much....
