Can anyone please help me in understanding the histogram on the ASIAir Pro? I am used to the histogram on the back of my old DSLR and 1/3 over. On this one on the AAP, I can’t quite tell where the graph begins. There is a zero at the beginning and is that level with the beginning of the graph? I hope that question makes sense. I will be shooting from a rural/suburban sky tonight and want to make sure I do not expose for too long on my ASI533MC.
