In the video it is interesting to note that even though he was using a scope of only around 1000mm F.L. he got the star backtracking along the line, and still got some star elongation with only 30 secs exposure. As the star seemed to be backtracking nicely, what could he do to improve his
P.A? I would have thought that if the star was backtracking along the line, then his P.A. would have been good enough to get round stars for
longer than that.
