Jim, I was thinking of trying this, too. I missed a perfect opportunity tonight, andat midnight it's already cloudy. It'll probably not be clear until April, when Orion has sunk low in the west...

I thought I'd try imaging through a V or R filter, for a couple seconds for maybe a thousand images. What a processing adventure that would be. Might be a data storage problem too. (I wonder if MaxIm can stack that many!)

Thanks for your note.
