This universal application is focused on helping you locate and enjoy any night of the year the 110 Messier astronomical objects. Many of these can also be observed with your eyes without any instruments. You can sort and filter by many criteria (magnitude, elevation, constellation, visible or not, object type) and keep track of observed objects. For each Messier object, you can obtain a photo, a description, a map and a plot of its movement during the night. A sky map shows you the positions of all visible objects now. The goal is to give you the needed information quickly without needing to go through menus or use the keyboard so you can spend your time observing. A dynamic map allows you to zoom and pan and include/exclude elements like star names and constellations. The app will point you to where in the sky is the object you are interested in and also show you what you are looking at. The app also helps you prepare if you wish to see all 110 objects in one night in March during a Messier Marathon. A planning tool allows you, for any night of the year, to find out how many Messier objects will be visible. Happy observations!
Requires iOS 5.1.1 or later. Compatible with iPhone, iPad, and iPod touch.
