Try this link, its contains a lot of info regarding Messier, his equipment and observing. I personally don't know how much mythology has grown up over the years. There are so many anomolies in the list to render it open to sceptism, M45 for example. How could that possibly be included? Its a very interesting thread though.
Hope this is of some help.
