Introduction to the Van Allen Observatory
The Trifid Nebula (M20) observed with the VAO

When using a simple optical telescope to observe the night sky, you could just randomly point it at various objects and locations.  However, you'll likely discover more fascinating sights if you plan your observations in advance. Historically, astronomers have used star maps and catalogs to predict when an object would be visible. Today, modern tools can simulate the night sky and viewing conditions. In this lab, you will learn about some of these tools and plan your own observation.

Software and websites such as Stellarium and Telescopius can be used to find out what objects will be visible tonight from 8-10pm in Iowa City.  After setting your date and time, you can search for objects from the appropriate list below, and view their rise and set times, altitude, and apparent magnitude.  You will need to make sure that your object is at 30 degrees altitude (or more) to be observable.  This ensures that it is visible above the dome of the VAO.
