Zero Second Exposure in Maxim with Atik 314L+?

[AstroManDan]

Hi,

I took an image of the full moon with a zero second exposure within Maxim DL using my Atik 314L+, and even the FITS header says 0 seconds - but is it really zero seconds?

Surely a zero second exposure would show darkness? How can I find out what the true exposure length was? Is there a min. exposure length you can do in Maxim or with the Atik 314L+?

Thanks

Daniel
