AAVSO Photometry CHOICE Courses

At present there are three AAVSO CHOICE Photometry courses, two for traditional CCD cameras and one for DSLR cameras. These are intense courses taught over a limited time and require daily commitment of time from each student to complete successfully. This includes time taking images as well as participation in discussion questions on the forum. Students will be asked to share their results with the instructor and with other students. An “open book” final test is required from each student. Please consult the syllabus to ensure you have the time commitment to take these courses.
