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.
