Messier List is an app containing the famous list of celestial objects compiled by French astronomer Charles Messier in the late eighteenth century. This list was put together by Messier to aid comet hunters while searching for comets by accurately cataloging the positions of objects that might be mistaken for comets. As such, his catalog contains all of the brightest and most prominent objects visible from the northern hemisphere and is extremely popular among amateur astronomers.
The Messier List app features descriptions of all the Messier objects, Fun Facts, their positions in the sky, photos where available and also indicates if the object is currently visible. It also provides a handy checklist for amateur astronomers who wish to check off the Messier objects as they view them during their stargazing sessions.
