Ask a Question About This Product

A full frame cooled CMOS Astrophotography Camera with 5.96um large pixels and a 24 megapixel sensor

The Sony Exmore IMX128 sensor has been used in a number of commercial products including the Nikon D600, 610 and 750 cameras, and the Sony DSC-RX1 camera.

In the QHY cameras, these sensors are implemented specifically for astronomical use with custom thermal noise reduction technology that does not affect the accuracy of the raw image.

Amplifier glow can also be an issue with some CMOS Astrophotography Cameras, but these new QHY models boast the rare capability of zero amplifier glow, no matter how long the exposure.

The image output is a true raw image, without any internal processing for maximum flexibility with image processing software.

Other features include a 128MB image buffer that helps tremendously with slower computers using USB 2.0,and when running multiple cameras using the same computer.

The optical window has built-in dew control and the chamber is protected from internal humidity condensation. The optical window is AR+AR coated, reducing halos around bright stars. IR blocking is not used so that the cameras can be used with maximum sensitivity to H-alpha and near IR light when desired, or a simple IR blocking filter can be attached for typical RGB imaging with IR cut. Each camera is carefully calibrated to high precision assuring flatness of the sensor to +/- 20 microns from edge to edge, eliminating the need for external adjustments by the user.
