Quick Overview

The QHY16803A is an all-in-one camera that includes KAF-16803 CCD sensor (36.8x36.8mmm area with a peak QE close to 60%) and a motorized filter wheel for 7 50mm square filters. This camera can be directly connected to the QHYOAG-L off axis guider. With the two-stage TEC reducing the sensor temperature to -40°C below ambient, and the extremely low thermal noise of this CCD, this camera produces an exceptionally clean image.

The KAF-16803 image sensor is a redesigned version of the popular KAF-16801 image sensor (4096 x 4096 pixel resolution), with enhancements that specifically target the needs of high performance applications. Improvements include enhanced quantum efficiency for improved DQE at higher spatial frequencies, lower noise for improved contrast in areas of high density, and anti-blooming protection to prevent image bleed from over exposure in regions outside the area of interest. The sensor utilizes the TRUESENSE Transparent Gate Electrode to improve sensitivity compared to the use of a standard front side illuminated polysilicon electrode, as well as microlenses to maximize light sensitivity. When combined with large imaging area and small pixel size, the KAF−16803 provides the sensitivity, resolution and contrast necessary for high quality digital astro-images.

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.

Single 12V power socket

This camera uses a single 12V IN power port. The power socket is threaded for a solid connection that will not accidentally disconnect. There is another socket connected in parallel with the input that can be used to supply 12V OUT to other devices.

Butterfly Shutter - long life and uniform illumination

Although the sensor has electronic shutter, this camera also has 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.
