With my F2 RASA in my Bortle 7 skies, I have to shoot 10 second lights. There’s a 7 second gap between frames, and shooting 10 frames takes 170 seconds. Since I shoot hundreds of frames, this is a problem. A lot of lost time.
Is this 7 second gap to be expected? Am I doing something obvious wrong?
Is there anything I can do to reduce the gap between frames?
