Hi Jeremy,
Many of my earlier images were taken using standard tracking from an alt/az mount and no guiding setup used.
The trick to alt/az no guiding is to use very short subs 5 seconds to 25 seconds and many of them 200 to 600 of them works well, the stacking process in DSS seems to round out most of field rotation in the central stars, however the edge of the field still shows field rotation in the stars so the final image always needs to be cropped to remove the curved stars.
Thanks, Wayne.
