The QHY 268M 26 MP Camera Review

Manufacturer: QHY

Price $2399 (bundles are a bit more)

The QHY 268M 26 MP is a monochrome astrophotography camera that features a 26-megapixel back-illuminated Sony IMX571 sensor. Because of the back illumination, the quantum efficiency is very high and the dark noise is very low.  The sensor also has a large full well capacity of 51ke- (at native 3.76um pixel size), which allows for long exposure imaging with a correspondingly low chance of pixel saturation.

The QHY 268M camera has a native 16-bit ADC, which provides excellent image quality with smooth gradients and high dynamic range. The read noise and the thermal noise are very low. This makes the QHY 268M a solid choice for imaging faint objects that require long exposure time to capture the greatest detail and to improve the signal-to-noise ratio.

The camera has a USB 3.0 interface and a 2GB DDR3 image buffer and USB 3.0 interface, which allows for fast image transfer and smooth live view. It also has a number of other features, including a built-in GPS module, a trigger input/output, and a choice of cooling options.

Overall, the QHY 268M is a great choice for hobbyists who are looking for a high-performance camera with excellent image quality. It is a versatile camera that can be used for small objects like planets or mid-size nebulae or galaxies.

Here are some of the pros and cons of the QHY 268M:


  • Excellent image quality
  • Very Low noise
  • Large 51ke- Full Well at 3.76um (binning makes it even higher)
  • Native 16-bit,  65536 Levels
  • USB 3.0 interface
  • 2GB DDR3 image buffer
  • Large 26 MP sensor
  • Supports both M54 and M48 thread adapters
  • Integrated dew heater
  • Monochrome camera takes full advantage of the sensor resolution
  • Short back-focus 12.5mm


  • Expensive
  • Small pixels translate smaller than full-frame sensor size
  • Some users have noted driver issues with N.I.N.A software


This is an excellent camera. Its high sensitivity and low noise make it superior to similar cameras in this price range. QHY is well-known in the astrophotography community for producing excellent cameras. If you don’t need a full-frame sensor camera, the QHY 268M is a good choice. If you want to take full advantage of its capabilities, you need to use a color filter wheel and several filters to create a color palette. Vendors often include a filter wheel and other accessories in a bundle that includes a filter wheel and off-axis-guider.

Verdict: 5/5 stars
