QHY All-in-One Cooled CCD Cameras
"A" Series Camera –Fully Integrated with Filter Wheel
The QH90A belong to the QHYCCD "A" series camera family. "A" stands for "ALL-IN-ONE". It includes a built-in motor driven filter wheel and it natively supports the medium size QHYOAG. The OAG can be installed on the camera solidly with six screws consuming a minimum of back focus, precious for some optical systems.
Internal USB Hub
In addition to the filter wheel and OAG, the "A" series camera also offers an internal USB HUB (2.0) providing two USB host ports and a USB to dual RS232 converter. A guiding camera, mount and electric focuser can be connected directly to this camera instead of the computer to reduce cable clutter and the chance of signal loss due to the long cables. A single USB cable controls all of the peripherals.
Butterfly Shutter - long life and uniform illumination
Although the sensor has electronic shutter, this cameras also have a mechanical shutter. This makes it possible to automatically take dark frames, unattended. The shutter is directly driven by a motor with no other moving parts. The working life is almost unlimited. The shutter has two sides that block light and open spaces in between. The fan shape of the blades creates even-illumination when opening, and even-darkness when closing for dark frames. This feature is of great benefit when taking flat frames or making photometric measurements.
We offer the following All-in-one cooled CCD cameras:
The QHY90A is an 8.6 megapixel integrated cooled CCD camera using the popular KAF-8300 4/3-inch monochrome CCD. This sensor has an array of 3358 x 2536 pixels at 5.4µm. The image area is a generous 17.9mm x 13.5mm.
The QHY90A has a built-in seven-position filter wheel that will hold 36mm round unmounted filters. An entire set of LRGB Ha OIII SII can be loaded at one time, avoiding the trouble of having to disassemble the filter wheel each time you want to change your filter group, making your imaging experience more enjoyable and more productive.
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.
