Last night afforded a decent opportunity to catch an interesting event, that is, the crescent moon was just above the Pleiades as they traversed the night sky. Using one photo, ISO 1600 f/8.0 1/400th of a second to accurately expose the moon, then one photo ISO 1600 f/5.6 1/50th to expose the stars, then superemposed the correctly exposed moon over the completely overblown moon in the pic with the stars visable rendered this image:
Both shots taken at 400mm with the 20D and Sigma 80-400 EX OS APO.
I'm going to try again tonight to see if I can get anything better, hopefully the moon is close enough to the open cluster still, anybody else have any experience? If the moon moved in the right way, then tonight it could be a little farther back and hopefully right inside Taurus, so I might be able to get a shot with the moon and the Crab Nebula visable together, that'd be kinda tight.
