ZWO ASI 294MM Pro - Colour Tele-Extenders Careful substrate selection and coatingZWO ASI294MM Pro Cooled Mono CMOS Camera. ASI cameras stand for excellent workmanship and have modern CMOS sensors installed. This versatile camera uses the state of the art "back illuminated" Sony IMX492 sensor. Sony specifies a sensor diagonal of 21. 63mm. However, due to sensor refinement by ZWO the true diagonal is 23. 2mm. The 4. 63m pixels of the ZWO ASI294MM Pro make this camera an all rounder with highest sensitivity for short exposure times
