Product Details

  • TheQHY QHY128C COLDMOS Astronomy Camera is a Cooled Color 14-bit CMOS astronomy camera with a 24 megapixel 35 mm format (36 x 24 mm). It uses an IMX128 sensor with a high dynamic range of more than 14 stops.

    Ultra High Performance The sensor has 4e- read noise at the lowest gain, 2.7e- read noise at unity gain(system gain = 1e/ADU), and 1.8e- at high gain.

    True and Completely RAW Image Output While the QHY128C has the same CMOS sensor as the Nikon D600 cameras, but with a True and Completely RAW image output. It does not perform any noise reduction and hot pixel removal. The QHY128C produces an image comprised of the original signal only, thereby maintaining the maximum flexibility for post-acquisition astronomical image processing programs.

    Cooling and Unique Thermal Noise Reduction Technology The QHY128C has an efficient 2-stage thermoelectric cooling, QHYCCD has employed a unique thermal noise control proprietary technology to reduce any CMOS sensor noise to a very low value without affecting the integrity of the raw image. 

    Zero Amplifier Glow The QHY128C will produce zero amplifier glow no matter how long the exposure. 

    128MB DDRII Image Buffer QHY128C has 128MB of image buffering in a DDRII.  Your frames will buffer in the cache for a greater frame rate retention. The image data is stored in the DDR immediately after acquisition and then transferred to the computer from this memory buffer.

    Anti-Dew Technology Full anti-dew technology is featured for both the CCD sensor cover glass and the sensor chamber optical window. There is an electric heating board for the chamber window to prevent the formation of dew keeping the sensor itself dry and QHYCCD's silicone gel tube socket design controls any humidity within the sensor chamber.

    AR+AR Optical Window To avoid halos around bright stars the QHY128C has an AR+AR coated optical window. This permits full access to the red wavelength of H-alpha and SII without attenuation by the window coating.  If your RGB color balance needs to not pass the near IR wavelengths above 700 nm, a separate removable 2-inch UV/IR filter with the desirable pass-band characteristics can be purchased and placed in a custom filter holder on front of the camera.


    * Each camera is carefully calibrated at the factory with a high-precision axis measurement device.  Orthogonal placement of the sensor is guaranteed to be flat to the image plane to better than +/-20 microns across the sensor from edge to edge, so there is no need to adjust for camera tilt absent mechanical errors elsewhere in the image train.

    An awesome full frame OSC camera!

    I recently got this camera and was able to image with it a few times. I wanted a full-frame OSC camera for galaxy season as well as broadband targets throughout the year, and I am very impressed so far! I use a $500 telescope (Orion 8" Astrograph) with this camera and both work surprisingly well together. I would suggest getting a IR-Cut filter if you plan on imaging an object near a very bright star though so you don't get star halos. Example images: The Iris Nebula: Markarian's Chain:

    I'm very happy with this camera

    Although I have had this camera for only one month, and haven't had much clear weather for actual sky testing, I am very happy with what I have seen so far. It is a technically fairly advanced camera, and I wouldn't recommend it for a beginner, but for someone with some digital astro-imaging experience, I find it quite exciting. It is my first full frame astro camera. I have not use SharpCap before (the camera control software recommended by QHY), but I find it powerful and pretty easy to learn and use. I strongly recommending reading the online manual before trying to use this camera. Included in the package were the camera, a 72mm diameter lens cap, the Center Angle Adjustment Ring (pre-set to be square with the optical axis), a 2-inch IR/UV cutoff filter, a small metal tube that can hold a dessicant and screws into the sensor chamber so it can be used for drying the air in the chamber, a 54mm male thread to 2-inch adapter so the camera can be slid into any 2-inch telescope focuser, a 2-meter long USB 3.0 cable to connect to a computer, and a power supply with a screw-on connection to the camera (100-240V, 1.2A, 50/60Hz input, 12V, 6A output). Other means to attach the camera to a telescope (such as a more dependable threaded attachment, which I used) or to attach it to a camera telephoto lens requires purchasing separately various adapters and/or threaded wide (48mm) extension tubes and/or 54mm filter holder and adjustment rings made by QHY. Since QHY128C package descriptions seem to vary by distributor, it would be good to verify exactly what is included in your package.
