The ToupTek IMX294C Colour is a cooled astronomy camera using the Sony IMX294 back-illuminated CMOS sensor. With a quantum efficiency of >80%, read noise as low as 1.42e- (in HCG mode) and large 4.63µm pixels, the IMX294C is an excellent deep sky camera for medium-long focal length telescopes.
The camera features relatively large 4.63µm pixels and a resolution of 10.3MP. The large full-well capacity of 66ke- means you can capture faint targets without overexposing stars. The IMX294C is equipped with 5Gbps USB 3.0 connectivity and 512MB of DDR3 memory resulting in fast transfer speeds and reliability.
The ToupTek IMX294C has zero amp glow, even at high gain and over long exposure times. The below image shows two 5-minute exposures at 20°C with different cameras. The ToupTek image on the right shows no visible amp-glow. Combined with its low dark current and powerful TEC cooling to -45°C below ambient, the camera is capable of teasing out fine details of faint nebulae.
The IMX294C features a built-in dew heater around the protective window with 4 levels of adjustable heating power. The camera includes an integrated two port USB 2.0 hub, allowing you to connect guide cameras, electronic focusers, filter wheels and other accessories.
