DSLR Photometry

AAVSO Photometry CHOICE Courses

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.

DSLR Observing Manual in Polish

The AAVSO DSLR Observing Manual is now available in Polish!

Thanks to an excellent volunteer effort by Ewa Stokłosa and Ryszard Biernikowicz with editing help from Krzysztof Kida, we now have a beautiful translation of the DSLR Manual into Polish. We hope that our Polish-speaking members and observers will find this manual helpful and will share it with their colleagues.
