Get Started With...

Citizen Sky is now officially permanent part of the AAVSO. In the coming weeks we will be moving additional content to the AAVSO site and freezing this site as an archive of the 1st three years of the project. Please visit the new landing page for future updates.

We have assembled a series of tutorials for getting you started observing and analyzing the data you or others have collected.  Along with these tutorials, the forums, and teams, you'll be doing science in no time at all.

5-Star Analysis with VStar

The 5-Star Analysis Tutorial is meant to introduce you to basic ways of data processing and inspection. It does not assume a background in astrophysics, statistics or anything similar. However, all good researchers need to understand what their data actually mean. So if you have never made a variable star estimate before, we strongly recommend first reading our 10-Star Observing Tutorial. That will give you an idea of where these data come from and what it means to actually observe a variable star.

10-Star Observing Tutorial

Observing a variable star takes practice. We have designed a training program that begins with stars that are easy to find and observe. Slowly the stars become more challenging as you go down the list. By the time you reach Epsilon Aurigae at the bottom of the list, you’ll be an expert variable star observer contributing real data to professional scientists

DSLR Photometry Tutorials

Photometry with DSLR cameras is a fairly new for amateur astronomers and can yield a lot of high-quality data in a fairly short time period.  Unlike single channel photometry or CCD photometry, few DSLR camera owners have an astronomical filter set handy, therefore the analysis of data from the camera can be tricky, but the DSLR Documentation and Reduction Team has gone a long way to simplify the process by creating tutorials for various photometric analysis software packages, and an Excel worsheet to aid in data analysis.
