I found this calculator for exposure that may be of help for some:
http://www.adidap.com/2006/12/06/moon-exposure-calculator/Tripod, cable release so you don't touch the camera, mirror up&electronic shutter (or exposure delay if no electronic shutter curtain), spot meter on the moon and look at histogram for exposure, turn off the IS/VR. The moon is a moving object so use at least a 1/125 sec shutter speed.
The blood moon will be low on the horizon, max about an hour before sunrise here in Arizona, so I am trying to find a good windmill to put against it.
I am going to use my 200-500mm @ 500mm, f/8 (my lens is max sharp at f/8), 1/250 sec, auto ISO, in manual mode for starters. Will be using manual focus so the AF does not hunt.
From the eclipse in 2015, I took this image at 550mm, f/6.3, 0.8sec, ISO 2500. A faster shutter speed would have been better as one can see some slight star trailing and the moon moves faster hence blurred some.
