It's really interesting to see that most of the objects are very close to
earth except for the globs and galaxies. As for the globs, I was really
surprised to see how they are all over the map, especially when compared to
the other types. Finally, for the galaxies, it makes sense that most of them
make an angle greater than ~45 degrees wrt the plane of the galaxy.
Thanks for the great tip! I really like to visualize the relative location
of the objects we look at.

Subject: [AZ-Observing] Messier Object Location App
Texas amateur astronomer Bill Tschumy has written a very nice little Java
application that shows the physical location of all of the Messier objects
with respect to the Milky Way's disc. The software is named "WhereIsM13."
http://www.thinkastronomy.com/software/software.html
Symbols for the selected Messier objects are plotted against edge-on and
face-on views of our home galaxy. Next time you're doing a Messier
marathon, you can gain some perspective on where you're actually looking.
