QHY16200A -
16mega pixels APS-H format astronomy CCD camera
Description
The QHY16200A uses a unique APS-H CCD sensor, a product of close collaboration between QHYCCD and their sensor supplier. This sensor is specially designed and manufactured with amateur astronomers in mind who need a mono sensor larger than APS-C.
APS-H Format CCD Sensor
The effective image area is 27mm*21.6mm. Compare that with the QHY8L APS-C format at 23.4*15.8 and you can see that the APS-H sensor is significantly bigger. No mono sensor exists between 8300(4/3inch) to 11002(full size) - enter the APS-H. At 16 mega-pixels, the APS-H format is suitable for most telescopes and, due to it's size, is also compatible with 2-inch filters.
The pixel size of this sensor is 6.0um*6.0um, which is slightly bigger than the 8300's 5.4um. The QE is expected to be similar or higher than the 8300. The 41ke fullwell capacity is much higher than the 25.5ke of 8300. This sensor has both a mono and color version. By default QHY16200A uses the mono version, with the color version being available by request (call).
"A" Series Camera - Fully Integrated
Both QHY90A and IC90A belong to the new 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 QHYOAG. The OAG can be installed on the camera solidly with six screws at minimum back focus, precious for some optical systems.
The filter wheel in the QHY16200A is a 5-position housing unmounted 2-Inch filters. The camera is compatible with the small size QHYOAG.
Besides the filter wheel and OAG, the "A" series camera has more to offer. An internal USBHUB(2.0) provides two USB host port and a USB to dual RS232 converter. Guiding camera, mount and electric focuser can be connected directly to this camera instead of your computer to reduce cable clutter and chance of signal loss. Only one USB cable is necessary to connect to the computer.
Butterfly Shutter - unlimited life and uniform illumenation
This camera uses a mechanical butterfly shutter that is frictionless. The working life is almost unlimited and provides uniform illumination of the sensor.
Single 12V power socket with screw lock and USB Clip
This camera uses a single 12V cable to power the entire system. The power socket is threaded so it can connect with the thread lock on the DC plug to get a solid connection. There is another socket which is connected with the input in parallel that can supply 12V to other nearby devices. Also, since USB is designed for commercial electric uses, it is not solid and the contact is not ideal for applications requiring high-reliability. It isn't uncommon for a telescope slew to pull the USB cable out of the camera enough to interfere with data transfer. In the "A" series design QHYCCD makes a unique stainless steel USB cable clip to improve securing the connection.
