Thanks Greg, I only used data that was no higher than 2.3" FWHM. It meant trashing a lot of data as the seeing has been variable of late at Clayton. Having an automated setup allows this luxury though.
How do you measure the FWHM? I find it a somewhat unreliable measure. In CCDstack you'll get quite different FWHMs if you click on different stars.

Greg.
