More DSLR photometry, this time by Mark Blackford.
Apparently saves you a filter wheel. That's nice. But you have to defocus to get around that bayer mask.
Amateurs can do some good science here with minimal equipment. He uses a 400mm telephoto and Canon DSLR. And adds to the store of human knowledge.
Quote of the talk:- "Amateurs with modest equipment can photometrically measure stars that are too bright for professional telescopes."
