The ALccd-QHY 695A uses the ultra-high sensitivity SONY ExView II CCD sensor ICX695. This six megapixel sensor has a quantum efficiency of almost 80%! In combination with the efficient, two-stage Peltier cooling, you achieve a delta T of 45°, which reduces thermal noise to a low level. With the ALccd-QHY 695A, you get a camera that produces impressive extremely low-noise images.
The SONY ExView II CCD sensor's full frame/progressive scan readout normally does not require a mechanical shutter. However with the ALccd-QHY 695A, you do not need to forego an (additional) mechanical shutter, which allows you to create automatic dark frames without having to put the cover on the telescope. You can use the mechanical shutter for other purposes, e.g. for long-exposure images when you see that your guiding is temporarily very poor - you can close the shutter and simply wait until the guiding runs smoothly again. The shutter is butterfly-shaped and, thanks to its shape, ensures significantly reduced gradients during the closing and opening process.
The integrated design will appeal to the user who wants to have an all-inclusive solution - camera, filter wheel and off-axis guider. This camera system includes all of these components.
The off-axis guider is screwed directly onto the camera system housing, so that you have a fixed and twist-proof adaptation. The direct screw connection extends the dimensions of the camera/filter wheel combination by just 10mm.
The integrated USB 2.0 hub offers two USB outputs for additional accessories, as well as a dual USB/RS232 converter. These connectors allow you to connect an electric focuser, a guide camera and your mount. This reduces many and long cable connections that, experience shows, can cause problems. Once you have connected all the peripherals to the camera system, all you need is a single USB cable from the camera to your PC.
To operate, the camera system requires a 12V power supply. The connector is screw-in and sturdily connected to the power supply plug.
We offer the filter wheel for seven unmounted 36mm filters.
