This page is being currently substantially modified. It will be reconnected as soon as possible, containing, when finished, all Messier objects (110). Actually, most of the whole catalogue will be retaken with high resolution telescopes. in order to have a definitive collection of all Messier objects.
A message will be posted in the Blog once this page has been uploaded, as well as every time that an object has been replaced by a new one (higher resolution).
Meanwhile, the objects considered correct can be found in their respective categories (Emission Nebulae, Galaxies, Planetary Nebulae, Open Clusters, Globular Clusters).
