Hi All,
Many thanks for all your comments, and yes, guiding/alignment was the problem, I sat at the scope/mount for a couple of hours last night and found that the drift (N-S) was a bit out of limits, so adjusted the mount to compensate, if its not spot on the guiding does a bit more work and shows up in F-10 Pix., also long exposures overhead show up the misalignment even though short ones (10 Min.) dont, a series of Pix. taken cannot be combined (aligned) as the stars in each successive pix. will be displaced by the drift, always something.
cheers.......Jim
