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.
