One of the most important feature on this camera is that it is cooled, which makes it perfect for long exposure sessions. The QHY290C has the capacity to cool 40ºC below ambient. Incorporated with anti-dew technology, the CMOS chamer is fully sealed and includes a silicon tube socket as well as a heater to avoid dew formation, so that users can enjoy a relaxed imaging session even on damp nights.

Perfect for both planetary and deep-sky imaging, made with Sony IMX290 colour CMOS sensor and a fast USB.3.0 interface, users can enjoy all levels of sky observation as this camera provides ultra sensitive and high frame rate photography capabilities.

Built-in 4 pins filter wheel connector as well as a 6 pins RJ11 guiding port.

Amp-glow suppression telenology to support a clearer background in long exposure sessions. This is particularly good for users who are looking to do deep sky imaging.
