Well, a few things are going to make it difficult:

1) Tomorrow night is the Carol Woods observing session ... not a dark site
2) The moon is pretty close to full (97% illuminated)
3) While S&T says it is mag 11, some say it is "coal black"
4) Various reports say the ephemera will change slightly as it passes

But the Clear Sky Clock is predicting good conditions, so we'll just have to take a shot.  I'm planning on dragging The Mistress out tomorrow to the meeting ...
