QHY 533M - Cooled BSI Monochrome Astronomy Camera - 1" Sensor - 110100

The QHY533M, shown above in top right portion of image (the color version is shown at bottom left), is a new generation of back-illuminated CMOS cameras with 3.76um pixels.  The QHY533M uses sensors that are similar to those used in the QHY flagship models QHY600 and QHY268, featuring low noise.

The QHY533M can be directly connected to the QHYCFW3S-SR without removing any part of the filter wheel (like the filter container). This provides a very short back focal length and that’s easy to fix! Besides, QHY533M + QHYCFW3S-SR combination can be easily connected to a DSLR lens, with only one additional adapter (sold separately).  

The QHY 533M comes with an additional tripod interface adapter, making it easier to shoot with DSLR lens.

BSI

One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor.

In the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something dim.
 

TRUE RAW Data

In the DSLR implementation there is a RAW image output, but typically it is not completely RAW.  Some evidence of noise reduction and hot pixel removal is still visible on close inspection.  This can have a negative effect on the image for astronomy such as the “star eater” effect.  However,  QHY Cameras offer TRUE RAW IMAGE OUTPUT and produces an image comprised of the original signal only, thereby maintaining the maximum flexibility for post-acquisition astronomical image processing programs and other scientific imaging applications.
 

Anti-Dew Technology

Based on almost 20-year cooled camera design experience, The QHY cooled camera has implemented the fully dew control solutions. The optic window has built-in dew heater and the chamber is protected from internal humidity condensation. An electric heating board for the chamber window can prevent the formation of dew and the sensor itself is kept dry with our silicon gel tube socket design for control of humidity within the sensor chamber.
 

Cooling

In addition to dual stage TE cooling, QHYCCD implements proprietary technology in hardware to control the dark current noise.

Amplify Control

Compare to the last generation of cameras for beginners, like the QHY183 or QHY163, the QHY533M has much better amplify control.

Free Adapter Kit Included

A free Adapter Kit F1 will be provided with QHY533M. 

QHY533M external use of threaded interface can be directly connected to the small filter wheel (CFW3S-SR). When the QHY533M + filter wheel combination are connected to a DSLR lens, only an additional DSLR lens adapter ring (sold separately) is required to complete the focus.
