New CHOICE Courses: Final days of registration!

"Visual Observing Basics" and "CCD Photometry, Part One" will both will run March 18 through April 12, 2013.  Visit the CHOICE homepage for more details and the registration link!

CCD Photometry, Part One

The AAVSO is rebuilding its CCD Observing Manual from the ground up, including a change of title: the Guide to CCD Photometry.  This semester we're teaching the introductory material for the guide to explain why you do photometry, as well as material on CCD calibration procedures to take your raw images and ready them for photometry.

This course will cover most of the technical material in "CCD Image Calibration".  Members who have successfully taken the Image Calibration course will be ready for Part Two of this course to be offered later this year.
