QHY410C

The QHY410C is a powerful full-frame CMOS camera designed for astrophotography. Let’s explore its impressive features:

1. Sensor and Resolution:

   • The QHY410C utilizes the back-illuminated Sony IMX410 CMOS chip, which is also found in high-end cameras like the Nikon Z6 and the Sony A7 III.
   • This 24-megapixel full-frame (35mm) sensor is mounted in a camera with regulated cooling and zero amplifier glow.
   • The combination of back-illumination and efficient cooling results in exceptionally low noise levels¹.

2. Quantum Efficiency (QE):

   • The QHY410C achieves an impressive 80% QE due to its back-illuminated design.
   • Unlike front-illuminated chips, where supporting electronics surround each pixel, the back-illuminated chip allows 100% of the light receptors to absorb and record light.
   • This higher sensitivity is ideal for astronomy and astrophotography¹.

3. Color vs. Mono:

   • The QHY410C is a one-shot color camera that uses a Bayer matrix to split light into red, green, and blue (RGB) channels.
   • Each cluster of colored filters corresponds to one color pixel.
   • The absence of noticeable cosmic ray hits and the ability to capture true color images make it a valuable tool for astrophotographers¹.

4. Applications:

   • The QHY410C is best suited for long-focal-length telescopes.
   • Its low noise and high sensitivity allow for stunning deep-sky imaging.
   • Whether capturing galaxies, nebulae, or star clusters, the QHY410C delivers exceptional results without the usual noise limitations associated with CCD cameras¹.

In summary, the QHY410C challenges the traditional boundaries of noise in astrophotography, making it a compelling choice for capturing the wonders of the universe. You can find more information about this camera on the Astronomy website or the QHYCCD website. 🌠

* 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.
