>>Click on the image and blow it up. You will see the camera is NOT tracking
at all. The stars are stretched from celestial motion.
It is a genuine short period photo without equatorial tracking of any kind.
I do astrophotography now and then. :-) YCS<<
Okay, I just did that and I have to agree now that the camera was not
tracking the stars after all. Apparently it had a relatively short
exposure...perhaps around 20 to 30 seconds maybe? If after blowing the image up there were
pinpoint stars, I'd still have a case....but I don't see it that way now. So
it appears that the guy had a genuine one exposure image for this wide angle
photo. Indeed it looks very nice and I have more respect for it now. :O)
