The Telescope Lecture

Tonight three people did presentations on how to use different types of telescope mounts.  I bet you wish you could have been there!   :-)  Standing and smiling is my friend Dave, who is a first class astrophotographer.  He is a master of doing these complicated photographs of faint galaxies that take hours of making multiple exposures and then combining them in photo software.  So Dave talked about the complicated process of polar alignment of some these tracking mounts.  I like his smile here.  And I am sorry for being so technical, two days in a row   :-)
