Product Details

QHY 8.6 Megapixel CCD Monochrome Astronomy Camera

The QHY90A is an 8.6-megapixel cooled CCD camera using the popular KAF-8300 4/3-inch monochrome CCD. This sensor has an array of 3358 x 2536 pixels with a 5.4um pitch. The image area is a generous 17.9mm x 13.5mm. The camera features 16-bit A/D to capture a huge range of detail in monochrome images.

All-in-One Configuration Includes Filter Wheel and OAG Support

The letter "A" is used by QHYCCD to designate a camera that is an integrated (ALL-IN-ONE) camera equipped with the essential integrated features needed for astrophotography. The QHY90A has a built-in seven-position motor-driven filter wheel that holds 36mm round unmounted filters. An entire set of LRGB Ha, OIII, and SII can be loaded at one time, which avoids the trouble of having to disassemble the filter wheel each time you want to change your filter group. The camera also supports integration with a QHYOAG off-axis guider using six M3 screw holes while taking up minimal back focus. (Off-axis guider is sold separately).

Integrated Control

The A-series cameras have a USB host interface that can be connected to a guide camera. Two serial ports are available for the equatorial mount and the electric focuser. Control of the camera, mount, guide camera and focuser can be managed through a single USB connection to your computer.

The QHY90A uses a single 12V power cord that can be secured with a threaded lock nut. It also has a 12V output socket that can power peripherals directly from the camera.

Butterfly Shutter for Uniform Illumination and Long Life

The QHY90A camera uses a mechanical shutter that has the shape of a butterfly. This provides even illumination as the shutter sweeps across the sensor to begin or end an exposure. The shutter is driven directly by the motor and has no other moving parts, making its working life almost unlimited.

Two-Stage TEC cooling

Integrated two-Stage cooling reduces the temperature of the CCD chip to 45 degrees C below ambient, resulting in very low thermal noise and a clean, long exposure.
