Product Details

  • QHY 533M Cooled Monochrome CMOS Camera

    After the release of the original color version of the 533 camera sensor, its popularity soared and it quickly developed a reputation as one of the best sensor values on the market due to its high pixel resolution, square sensor shape (perfect for sharing images on social media), incredibly low noise and high sensitivity, all at a lower cost than most comparable cameras. The only complaint was that the camera was only offered in a color sensor version … until now.

    With the 533M, you get all the benefits of a professional monochrome camera, without the higher cost of larger sensors. There’s no need to purchase expensive 2” filters to cover the sensor, the QHY 533M camera requires only 1.25” filters, cutting your filter costs substantially. It can also interface with your DSLR lenses, and includes a 1/4” tripod mount, meaning you can make use of the glass and tripod you already own with this camera.

    QHY533M — Purpose-built Astrophotography Camera

    A few of the most impressive specs of the QHY 533M includes active dual-stage cooling, which reduces sensor noise even further, anti-dew technology with built-in heaters to keep the optical window clear from fogging at all times, and a compact form factor making it useable on any system.

    This CMOS camera’s pixels come in at 3.76um across, and it records in 16-bits at a 3003x3003 resolution with true RAW image output. The sensor is back-illuminated, removing all amp glow, meaning your photos will be true to life. It’s small size and impressive specs make the QHY533M perfect for portable astrophotography setups and front mounted telescopes such as HyperStar configurations or Celestron RASAs.

    QHY 533M 1” 9MP Camera Sensor

    The 533M’s 9MP, 1” sensor ensures that even the finest details in your images can be resolved clearly and consistently, while the internal 1GB buffer allows for 27 frame captures per second in 8-bit mode, or 18 frames per second in full 16-bit mode. This camera helps bridge the gap between budget and professional offerings for those who want to delve into the realm of full control monochrome imaging.

    QHY CFW3 Small 7 Position Filter Wheel - 1.25"/31mm

    With the introduction of their innovative new 3rd generation models, QHYCCD has revolutionized what one can expect from a filter wheel moving forward. Incorporating an ultra-thin stepper motor drive, this 20 mm thick filter wheel is capable of fully automatic filter switching. It offers seven positions for 1.25" or 31 mm round filters. Maximum filter thickness for mounted filters, excluding filter thread height, is 10 mm. Learn more about the QHYCFW3 Filter Wheel and its impressive features in the comprehensive video below!


    Ultra-Thin Hybrid Stepper Motor Drive

    QHYCCD has chosen to use an ultra-thin, high quality hybrid stepper motor for the design of their third generation filter wheels. When compared to PM stepper motors used in many filter wheels, this hybrid stepper motor offers improved precision and a smaller step angle. An enclosed motor prevents the accumulation of dust for enhanced reliability and longer life. In addition, as filter rotation is reversible, the carousel can be rotated clockwise as well as counterclockwise for convenient filter access.

    Friction Drive with Zero Backlash

    Regarding the evolution of the motor drive, QHYCCD's 2nd generation filter wheels used a gear drive while their 3rd generation filter wheels use a friction drive that results in zero backlash during operation.

    USB Serial Port Switch

    Incorporates a serial port switch to enable fast shifting between serial and USB communication modes.

    USB Powered

    Supports QHY 4-pin connection control mode, contains open source Arduino-compatible firmware, and is designed to work with a similar sized QHY Off-Axis Guider (OAG).

    Beautiful Appearance

    The main body of this QHYCCD 3rd generation color filter wheel is cut from a single precision CNC machined piece of aluminum. It boasts a skillfully crafted and elegant finish. As soon as you hold this filter wheel in your hands, its small design will prevent you from ever wanting to put it down!

    The filter carousel has been specially designed to allow the installation of unmounted filters with varying thickness. Mounted filters below 10 mm in thickness can be installed while unmounted filters of different thicknesses can also be mounted to the same filter disc. This makes filter positioning quicker and more precise.

    QHY Small Off-Axis Guider

    The Small Off-Axis Guider by QHY has 35 mm to the center point. It is a thin and solid design only being 10 mm thick. Adding an M42 thread adapter ring will add 3 mm for a total thickness of 13 mm. There are six 3 mm through holes in the OAG for direct connection to the QH-QHYCFW2 and QHY A-series camera.

    The prism position can be adjusted and can be locked down to fix its position. The prism is 8 mm x 8 mm size and the aperture between the prism and mirror is 8 mm in diameter. The QH-QHYOAG has a multi-thread 1.25-inch focuser build in which has a locking thumbscrew to hold the guide camera after focusing.
