10-Star Tutorial in Arabic

Thanks to volunteer Rani Ahmed, the 10-Star Training Tutorial is now available in Arabic!

We hope that new observers will find this tutorial very useful for learning how to make their first variable star estimates. Since no prior experience is required, the 10-Star Training Tutorials are also ideal for use in schools and clubs.

In addition to the English and Arabic versions, the 10-Star Training Tutorial is available in Polish, Turkish, and Chinese. There is also a Southern Hemisphere version available in English, Spanish, and Portuguese.

CCD Photometry Guide

The AAVSO Guide to CCD Photometry, first published in September 2014, is designed to be a basic introduction and guide to using CCDs to perform photometry of variable stars. With care, you can use a backyard telescope to obtain astrophysically useful data that matches the quality of those produced by professional astronomers, using exactly the same principles and techniques that are used at larger research observatories around the world.

New Chinese Visual Observing Manual

I am very pleased to announce that we now have TWO Chinese translations of the AAVSO Manual for Visual Observing of Variable Stars available for downloading. The newest addition to our collection of Manual translations is in "Traditional Chinese" which is used in Hong Kong, Macau, Taiwan and parts of southeast Asia. This beautiful translation was done by Tao Fan-Lin (陶蕃麟) who is the Director of the Taipei Association of Astronomy Now.

You can get both versions of the Chinese Manual here:
