Colin: For the landscape, based on my previous results, landscapes typically need 1-4 seconds (depending on how much detail you want) at ISO 100, f/4. Obviously can convert this to whatever f/ and ISO you are interested in.
Joe: I had never seen your light curve. Very nice. What was the altitude of the Sun during that eclipse?
Before thinking too much more about this, I am going to run some of my own quantitative tests using my past sequences. I will produce some light curves of my own, in ADU, of the sky and landscape.
