Did all that. The elongation is from a 1 sec exposure at 500mm. The
Astrotracer should work immediately.

Shot at 170mm. The 500mm shots were "elongated". Will try again with the
Astrotracer tomorrow, clouds willing.
One problem with astrotracer is that it won’t work at anything less than 10
seconds, which is way too long.
The elongation has to do with those points being so small that any vibration at
all show up. You have to tighten everything down very solid, every adjustment
on the tripod tight, you need to use a 2 second delay on the shutter release
AND you need to use a cable release or remote trigger.
