Messier Facts

[bendiddley]

Does anyone know where I can find a good source online that gives me facts about each Messier object? I've found a couple of places (wikipedia, astronomy factbook) but sometimes there is all the info I want and sometimes not enough, which means i have to go looking for it on other websites and often each site contradicts the other. The main info I'm looking to find out is magnitude, age, size and distance. I'm trying to add information to my bespoke star charts and just want to include a quick summary of each object from a reliable source that has this info and so I don't have to go searching other sites each time.
