A
Messier Marathon is an astronomy observation session that last
one night usually in March. Its goal is to locate as many as possible of
the 110 objects in the Messier catalog but it can be practiced any time
of the year,
This
application’s goal is to help you for the marathon or just to observe
Messier
objects any night of the year by:
Providing you a list of
the 110 objects that you can sort by magnitude,
by Messier number
, by
altitude,
by constellation or by
suggested observation order. You can also
filter out those objects that are currently not visible and filter by
objet type.
For each Messier object,
you can obtain a photo, a description, a map and a plot of its movement
during the night.
You can also specify for
each object if you were able to observe it and give it a rating.
A
general sky map
shows you the location of all the
Messier objects currently visible.
A planning tool allows
you, for any night of the year, to find out
how many Messier objects will be
visible.
Happy observations
