I wonder whether some of you use such a chip for photometry. There are currently an SX and an Atik models that are fitted with ICX 694. Pixels are very small, only 4.54 microns but I am planning to use this chip with a short focal lenght refractor (450 mm) and with a Newton 200 mm f= 800 mm.
 I would be glad to hear opinions from you about linearity, bias level, noise etc.
