QHY410C

The QHY camera is a 14-bit, back-illuminated (BSI) CMOS, full-frame format. 5.94 um pixel size, 24MP color cooled camera. 120ke- full well. It is best suited to long focal length telescopes. 

This is like the Back-illuminated (BSI) version of QHY's QHY128C camera.  

New Back-illuminated sensor: IMX410: 24.6MP BSI CMOS sensor. Based on Square Pixel Array Technology. At Full readout mode, the sensor can deliver 24 MP Stills at 19.2fps.

The QHY QHY410C CMOS Astronomy Camera is a Cooled Color 14-bit CMOS astronomy camera with a 24-megapixel 35 mm full-frame format (36 x 24 mm). It uses an IMX410 sensor with a high dynamic range of more than 14 stops.

Ultra-High Performance The sensor has 1.6e- read noise at the lowest gain, 3.8e- read noise at unity gain (system gain = 1e/ADU), and 6.1e- at high gain.

True and Completely RAW Image Output While the QHY410C has a similar 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 QHY410C 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 QHY410C 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 QHY410C will produce zero amplifier glow no matter how long the exposure. 

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 QHY410C has an AR+AR coated optical window. This permits full access to the red wavelength of H-alpha and S-ii 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.
