I can obtain 120 second round stars with my mount /telescope without guiding. Maximdl says less than 10% on the flatness of the stars at .78 arcsec/pixel.
Could I use astrometric resynchonization with maximdl between images to obtain exoplanet data rather than guiding? It takes less than 2 seconds. Shorter than the image download.
Thanks,

I use it. Solves and saves the solved images too.

Jeff,
It would be interesting to see how accurate it gets the target back on the same pixels.

My experience is that it is not ideal. But keeps me within about 5 arcseconds or 5 pixels. <4 arcsec FWHM stars. In my case it works well from about 58 degrees down to 0 degrees DEC. Further north it oscillates, Futher south are trees. I am hoping that I have some gain or agressiveness setting not optimal. Redoing polar alignment has very little effect.
