Have you even taken out your Alt-Azimuth telescope out of a casual session, looked up and thought, "Hmm, I wonder what's up there... maybe just above the second to last fencepost?" AstroPoint will allow you to enter a range of min/max Altitude and Azimuth and present a list of Messier and choice NGC objects currently within that 'Sky Window'. The resulting objects are listed by visual magnitude to make your evening of driveway observing more enjoyable.
