Hi Robin,

If you don't have any dust donuts from filters etc., then you could just build a library. Use CCDSoft to make flat masters for each filter. Try rotating the camera for one filter to see if the vingetting changes.

As you have a lightbox, just take them after your imaging run.

Cheers
Stuart
