Mike,

Thanks for that info. Yes I have very dark skies. Will try a faster film and longer exposure.

 

Thanks,

These are probably not long enough exposures to show more than the brightest stars. I don't know what the reciprocity of your film is like, but it is a slow film for that short of an exposure. These would account for the dark spots on tne neg. At that f ratio, you should try to go about 5 or 10 minutes if your sky will allow it. Wide angle, fast f-ratio stuff really demands that you have a dark sky.

Mike,
The exposures were each 30 seconds long. Pictures were taken of bright abd faint stars including a -1 Iridium Flare.
