Subject: chip size, Flea 2...

Hi Milton, The Sony site you`ve directed me to gives a chip size for the ICX424AQ chip used by the Flea 2 as 5.79mm (H) x 4.89mm (V). However, when I enter the details for the Flea 2 into Astroplanner`s (v2) Imagers window in "Resources", (7.4um x 7.4um & 648(W) x 488(H) as number of pixels) I`m getting a reading of 4.80 mm(W) x 3.61 mm(H) for sensor size. Which of these would be more accurate? Mark.
