L data came in at 2.7" (x) / 2.55" (y) FWHM... keep in mind this is at 0.5"/px so it's heavily oversampled and will thus look softer than it would at >= 1"/px

Hi Lee,
2.7 to 2.5 arc seconds FWHM is fairly good -
so yes it should have looked slightly sharper.
Why have you had optical issues lately - what's changed?
cheers
