The monochrome CCD cameras have the great advantage of having a much higher sensitivity than color cameras. So, in addition to allowing you to record weaker details, these cameras are perfect when used with the narrow-band filters (such as H-alpha, O-III or SII) that allow you to remove light pollution by greatly increasing the contrast of images. This makes it possible to photograph deep-sky objects (like nebulae) also from places with light pollution.
But mono CCD cameras are usually very expensive and this stops many amateur astronomers in the purchase. The QHY9 monochrome CCD camera changes the rules offering a Kodak KAF8300 monochrome sensor with large dimensions (18.1 x 13.5mm) and high resolution ( mega pixels - 3358 x 2536) at a great price. All of this combined to the double Peltier cell cooling system (which takes the sensor's temperature down to -45°C than the external ambient temperature incredibly reducing electronic noise in long exposures typical of astrophotography) and to an advanced 16 bits electronic A/D converter.
Technical comment by Filippo: "The QHY9 monochrome CCD camera is perfect for use with apochromatic refractors. In fact, the small pixels are perfect for these telescopes with short focal lengths (allowing you to record images with excellent spatial resolution) while the big size sensor helps to frame objects, even the largest ones in the sky".
This will let you record images even with very long exposure times. The QHY9 cooling system also allows you to precisely set the sensor working temperature: this way will be sure that the camera will record all pictures at the same temperature, regardless of the ambient one variation. This is critical to correctly calibrate the images being processed.
