The comet fills the 90mm frame quite nicely and I took a roll of Fuji Super G 800 with exposures from 10 seconds to 1 minute, all wide open at f2.8. I just got my negatives back and the results are rather disappointing. Stars start to trail for all exposures longer than 15 seconds and the negative is too thin for the exposures below 15 seconds. The proper exposure is in the neighborhood of 40 - 60 seconds. I am thinking about building a simple device to track the apparent motion of the sky during the long exposure. I found the device described in some Astronomy book. Stay tuned for results. >Michael
