Thanks for the references. This underscores the fact that if, on the other hand, the aperture and exposure time are set for recording details in dark areas, guess what's going to show up in the sky? One benefit of the time exposure streaks is that one can easily discriminate between the star images and cosmic ray/bad pixel/etc. artifacts.

Nice photos! Wonderful to know there are may more that will be taken.
