| | Take a look at what stars, constellations, planets, and objects will be up during your excursion. There are a number of tools to accomplish this. You don't need to plan every object you will look for, but it helps to know what is going to be up there. | | | Planispheres | The night sky has seasons. By this I mean that in the evening winter sky, the constellations Orion, Perseus, and Auriga are overhead. In the summer, stars of Cygnus, Aquila, and Lyra form the "Summer Triangle" overhead. A planisphere allows you to dial in the month and time to show only the constellations that are overhead at that time. | | | Star Charts | Star charts come in different shapes and sizes. There are fold out maps, bound books, laminated boxed sets, spiral bound. | | | Books | Books are a good supplement for charts. Most often I use them before and after an observing session to learn more about what I observe. How far away is M13, how big is it, how old is it... | | | On-line resources | There are a number of on-line observing resources including on-line versions of star charts, planispheres, satellite predictions, | | | Astronomical Software | | | | Magazines | Sky and Telescopes "Sky at a glance" |
