Astroimager output format3/23/2023 This medium format Grade 1 or better CCD chip has a peak QE of 77% in yellow light, and 65% at 656nm. The Trius SX-694 monochrome CCD camera is fitted with the Sony EXview ICX694AL high resolution sensor, with an array of 2750 x 2200 (15.98 mm diagonal), 4.54uM square pixels. Starlight Xpress Trius SX-694 CCD Camera: Starlight Xpress 7x1.25 Midi Filter Wheel Combi with Trius Pro-694 Camera and Lodestar Pro CCD alignment screws are provided for setting the chip parallel to the focal plane. Size: 75 x 70mm black anodised aluminium barrel with 42mm 'T2' thread at the CCD window end & input/output plugs at rear. Cooling system: Regulated set-point cooling supply with thermoelectric cooler to give a minimum CCD temperature of approximately -40C below ambient.
