multi-star guide algorithm reduces seeing effects


Hi

Until Hy's multistar and RA GPG, I always used PHD2's single star, which seemed better than anything EKOS could offer at the time.

Internal multistar reduces the FWHM of my images by at least 0.2 in comparison, and that's on a bad night. I found 2.5s to be the optimum guide frame exposure using a 60mm f4 guide telescope and 3.5s for an OAG at 1200mm. But hey, these are gut feelings, nothing scientific.

Are we now saying that shorter exposures are better?
Cheers
