Hi,
from what I understand, only 1 image per night is needed from now to December 31st (per filter).
As I probably won't be able to shoot every night, I'd like to know if a several hours shoot on the same night would be interesting or not ? (I have only chromatic filters)
Unless a new giant flare goes off (unlikely), all changes are very slow, with a period > 3 week (not clear, 22 and 42 days have been suggested in the literature).
