Miller Planispheres are the premiere star finder. Durable plastic disks and accurate cartography with instructions right on the back. The Pocket version is 5.5" diameter. The model latitude is 22.5 N.
Special Note: Having the right tools for observing is important. A planisphere is essential. Ours is made with heavy duty plastic (never accept cardboard - a few outings in the nighttime dew will ruin it). Just dial the date and time and you'll see what's in the sky for that moment. Rotate the time dial to simulate sky motion... like having a personal planetarium. Pick your favorite constellation, put it on the eastern horizon to determine the date and time to begin seeing it.
Excellent for nightime navigation. Use your compass to determine your azimuth, look in the sky for which star in which constellation is at that azimuth. Then for 15-30 minutes head for that star and you are maintaining the proper azimuth.
