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.
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:
This translation would not have been possible without the hard work and dedication of volunteers Fatemeh Bahrani and her colleagues, Ali Honarmand, Fateme Kayanikhoo, Mozhde Mohamadi, Sajad Safari, and Arezoo Saleki of theDr. Hesabi Institute in Shiraz, Iran (http://www.dr-hesabi.org).
The Manual for Visual Observing of Variable Stars has been updated to reflect changes to the VSP and WebObs that happened when the new website was launched last summer. This mostly affects Chapters 2 and 7. To download these and other chapters, or the entire Manual, please click on the link below:
