Amateur Astronomy Guide. Entries for the 110 Messier objects. These include (public domain) images and some commentary. A lot of these objects are visible using good binoculars and all
are visible using a small amateur telescope.
Maps of all the constellations visible in the northern hemisphere with the location of all the Messier objects marked.
Links from the maps to the information pages and to neighboring maps. Apologies to those of you down under. Hope to get there eventually.
