Observing Manuals

We have a number of observing manuals, each one dedicated to a different type of observing technology.

These manuals are written for those with some background and familiarity with the various technologies. Those brand new to variable star observing may be more interested in our Getting Started Tutorials.


The AAVSO is building a suite of tutorials and documents aimed at those with absolutely no experience with variable stars and very little astronomical experience of any kind. These tutorials walk you through a basic concept of variable star science and then provide a list of challenges to apply the concepts.

Contact us when you have completed a tutorial and we will mail you a certificate.
