I have a superb FLI MIcroline 8300 (arguably the Rolls Royce of the KAF8300 camera world) that has been recently serviced by FLI.
It cools down 55-60 degrees C below ambient. I often use it at -40C.
Its extremely clean from -15C onwards. There are no defects in the chips images. It has fast downloads (about 1 second for a full frame image) , RBI control, robust body and small and lightweight. Good anti reflection coatings on the CCD window. Argon filled CCD chamber.
Selling to fund another project otherwise I would continue to use it.
AUD$3975 including shipping to Oz.
