I was playing around with gphoto2.
I got a remote dark frame with following settings:
Switch to bulb mode => gphoto2 --set-config shutterspeed=0
Take a remote dark frame => gphoto2 --set-config bulb=1 --wait-event=0s --set-config bulb=0 --wait-event-and-download=2s
How am I gonna make this work with Ekos? I use gphoto2 lib in Ekos for my EOS 450D.
