As we move through the review of each Messier object, we thought it would be fun to start doing the same for constellations. Therefore, to tie the two series and resources together, it made sense to detail which constellations have Messier objects, which objects are in them, and when they are visible all in 1 chart.

There are 88 IAU constellations, but there are only 34 that contain Messier objects. This means that there are 54 constellations that do not contain Messier objects, some of which are too far south to be visible from France.
