Hello folks, I have been playing with dithering and the other night using APT and PHD my dither's all kept getting "timed out"
I was exposing for 400 sec with a 50 sec pause between frames and on the PHD settings time out time was 60 secs- the first frame in a series said it dithered then the rest of the frames timed out?
What do I need to change to get it to consistently dither?
