I was poking around looking at astro stuff on the net a week or so ago,
and came across some interesting data at SEDS:
History of the Discovery of Deep Sky Objects:
http://www.seds.org/messier/xtra/history/deepskyd.html
It is also interesting to see how many objects were known before
Messier. I thought it would be a fun project to observe the pre-Messier
object in their order of discovery....
