Those are some very impressive astrophotos. Your guiding is outstanding.
What kind of a drive were you using?

Richard,
thanks for your kind words. I guided by hand... on a good vixen
super polaris mount. Perfect polar alignment is a must, and also an
eyepiece with a grid. My experience tells that 135mm (maybe 200mm) is
a limit for good consistency of results. For the time my limit is
around 10/15 minutes.
