QHY QHY90A Monochrome CCD Camera


The QHY90A employs the well-known 4/3" 8.6 mp KAF8300 CCD sensor found in several astronomy camera models.

Fully Integrated "A" Series Camera

Belonging to QHY's new "A" series "ALL-IN-ONE" camera family, the QHY90A incorporates a motor-driven 7-position color filter wheel for unmounted 36 mm filters, as well as a butterfly-shaped mechanical shutter for consistent illumination. It also offers native support for the QHY OAG-S Off-Axis Guider, which is sold separately. The QHY90A has six M3 screw holes for solid OAG installation while taking up minimal back focus.

"A" series cameras have more to offer in addition to the filter wheel and OAG support. An internal USB 2.0 hub offers two USB host ports and a USB to dual RS232 converter for attaching guide cameras, mounts and electric focusers directly to the camera without having to use a computer. Instead of multiple long cables leading to clutter and the possibility of signal loss, with the QHY90A, you need only one USB cable.

Butterfly Shutter - Virtually Unlimited Life and Uniform Illumination

The QHY90A camera uses a mechanical shutter in the shape of a butterfly that is directly motor driven. This shutter is only one component and does not cause friction to other components. It has a virtually unlimited operating life to go with a uniform illumination feature. This shutter is also double sided to cover the light, one side to open the shutter, the other to close the shutter.

12V Power Socket

This camera is powered by a single 12V socket. This power socket connects with DC plugs using thread lock for a reliable connection. An additional socket connected with the input in parallel is also available to provide the 12V of power to any external device within reach.
