 Starlight Xpress SXVF-H9 and H9C Cameras The SXVR-H9 is an advanced, very high-resolution cooled CCD camera, especially designed for astronomical imaging. It is an upgraded version of the SXVF-H9 and now incorporates regulated temperature control and is housed in a smaller body. It is a third generation version of the very popular HX916 and incorporates many substantial improvements and extra features. These include a built-in, fully programmable, USB 2 super-fast computer interface (USB 1.1 compatible), an optional add-on autoguider output and integrated dual serial ports for filter wheel and telescope control. The SXVF-H9 uses a Sony ICX285 ‘ExView’ progressive scan CCD, with 1392 x 1040 6.45uM pixels in an 8.98 x 6.71mm active area. ExView devices have excellent quantum efficiency, with a broad spectral response peaking at around 65% in the green, and an extremely low dark current, well below that of any comparable CCD currently available. While this device has an excellent blue light sensitivity, it also has a strong infra-red response, which makes it ideal for all aspects of both planetary and deep-sky imaging, especially with an H-alpha filter.
