Yes, I have still verified that for large ranges of brightness, ordinary cameras are not very suitable. I am currently in the process of making a photometer with a photocell applied to the focus of a telephoto lens (really bad optics) with a diameter of 110 mm. However, the quality of the image matters little as I only need to measure the illuminance. I don’t remember if I mentioned that my programme is concomitant with the Perseid shower. It is a job that should be a novelty in the amateur field. Thank you Peter.
Greetings to all the friends who have listened to me and to whom I may have annoyed a little: the passion for Urania is strong.
