@celestiaforequestria IGNORE WHAT I JUST SAID! I mathed wrong. I forgot to change the f-stop, I was calculating at f4.0. Let's assume you have a 50mm lens that can be stopped down to f/18, and set your focus distance to 25ft, then things from 12.5 feet out will be in focus. f22 would you give you focus from 10 feet out to infinity with the focus distance at 20 feet, but you'd definitely need a long exposure, and seeing as the moon's luminous would lose all of it's detail. So if you want the moon to be in focus, and detailed, definitely going to need two exposures.
