I'm not sure I understand the urgency to expose the "Saturnless" M1 image
near the time of the transit. M1 isn't going to change on the time scales
that we're talking about (IMO changes in M1 itself might be detectable on
the time scale of years, unless you are talking about Hubble-type
resolution, then maybe months).

So, unless we're talking about image ethics, does it really make a
difference whether the Saturnless image is taken a day before or after the
transit, a week, or a month (or more)? And even including image ethics in
the equation, does it make any difference (i.e., the difference between a
day or a month before or after the transit)?

IMO, the answer is "no".

And yes, at least from upstate NY, it's almost certain to be cloudy for the
transit itself.
