At present there are three AAVSO CHOICE Photometry courses, two for monochrome CCD/CMOS cameras and one for DSLR cameras. These courses require daily commitments of time from each student to complete successfully. This includes time taking and processing 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.
