BTW- you can't measure FWHM post processing. the individual images (this
is 10x10 min) should be measured individually. What are you using to mesure
it, anyway? Previous versions of Maxim DL are inaccurate before 3.0.

Hi Sean,

I'm measuring your best stars at 1.85 pixels or 5.76 arc seconds FWHM with
my program, have you measured the original?

Nice image BTW, 100 minutes is a long time even for film were you un-binned?
