Please select your camera options above. While Cloud Break Optics tries to stock a variety of camera options, we simply cannot stock all of the possible configurations of QSI cameras.  If you select a combination that is out of stock, we will order it and have it shipped as soon as possible from QSI.  If the website indicates your combination is "unavailable," that combination is not valid (i.e. 2.156" adapters are available for (w)sg cameras only and cannot be configured on any other camera cover configuration).

QSI 683 8.3mp Color 
Cooled CCD Camera

  • Single-shot color 8.3mp Kodak KAF-8300 sensor
  • USB 2.0 High-Speed16-bit output
  • Dual read rates of 800kHz and 8MHz
  • Air cooling to 45C below ambient
  • Available internal color filter wheel (CFW)
  • Available Integrated Guider Port (IGP)

    The QSI 683 model camera employs an 8.3mp Kodak full-frame CCD image sensor with microlens technology. The increased Field of View, high quantum efficiency, wide dynamic range, dual read rates, low noise performance and internal 5 or 8-position color filter wheels make the QSI 683 ideally suited to a broad range of demanding scientific and astronomical imaging applications.

    The compact design of the QSI 600 Series allows the 683 to set a new benchmark for cost and size in a high-performance, full-featured scientific CCD camera. With optional features and upgradeability, the QSI 683 can be tailored to fit your needs today and in the future.

    The QSI 683wsg is available with an Integrated Guider Port (IGP) allowing astronomers to guide using the light from the main telescope while picking off the light from the guide star in front of the filters

    The 683 camera system is supported by industry leading image acquisition software plus a full camera control API is available for creating custom Windows or Linux applications.

    QSI 600 Series Cameras
    with Integrated Guider Port 

    QSI WSG models are an innovative new addition to the QSI 600 Series family of cooled CCD cameras. The WSG has an internal mechanical shutter and filter wheel like the 600 Series "ws" models, plus it adds an Integrated Guider Port. This allows guiding using the light from your main telescope while picking off the light from the guide star in front of the filters. The WSG option is available on all 600 Series models. 

    Selecting the best guiding solution has always required a compromise. The Integrated Guider Port (IGP) of the WSG solves many of the problems associated with existing guiding solutions. 

    The Right Guiding Solution

    Guiding with a separate guide scope provides the most flexibility, but differential flexure can be an issue, especially with long focal length scopes. With an internal guide chip, you're forced to guide with light through your filters and you can't guide at all while the shutter is closed or an image is being downloaded. This is especially problematic for narrowband imagers. To get around those issues, you could add an external off-axis guider, but a traditional OAG can add an inch or more of back focus plus more weight and two new mounting surfaces that need to be held rigidly.

    Flexible Guide Camera Options 

    The Integrated Guider Port (IGP) built into 600 Series WSG models is designed to support any camera with 12.5mm of back focus or less that can be attached using C-mount or T-mount threads. Many cameras are designed with 12.5mm of back focus to be compatible with CS-mount lenses which use the same thread as C-mount (1" x 32tpi) but with 12.5mm of back focus instead of 17.5mm for C-mount.  Alternatively, you can select the 1.25" Filter Thread attachment to achieve 13.4mm of back focus.

    Easy, Rigid Guide Camera Focusing 

    The guide camera attaches to the WSG using a C-mount or T-mount threaded adapter (specified at time of order). The threaded adapter sits on top of the focus ring and allows the guide camera to be rotated to any position. The focus ring threads onto the focus base to allow 3mm of travel when focusing the guide camera. Once focus is achieved, the focus ring is locked with a set screw. The guide camera can still be rotated manually if desired without changing the focus. The end result is a rigid, easily focused guide camera that will not move or flex while your mount tracks the apparent motion of the night sky.

    Guide with Light From 
    in Front of the Filter Wheel

    The QSI 600 Series WSG models solve the problems with other guiding solutions by integrating a precision off-axis guider directly into the camera body with the pick-off prism positioned in front of the integrated color filter wheel – right where it belongs.

    Never Struggle With Finding a Guide Star

    One of the main challenges when using a camera with an internal guide chip is to find a star bright enough to guide by within the limited field of view of the internal guide sensor. When shooting through red, green or blue filters, ⅔ of the available light is blocked by the filter and not transmitted to the internal guider chip, guaranteeing lower signal-to-noise stars for guiding. This problem is compounded with narrowband filters where as little as 1% of the total light from a star reaches the guide chip. By positioning the pick-off prism in front of the filters, you always have all the star's light available for guiding.

    WSG Supports Fast Optical Systems 

    By integrating the Guider Port into the camera, we're able to position the pick-off prism very close to the internal filter wheel adding minimal backfocus and eliminating any possibility of flexure or rotation compared to a traditional OAG. The large ½" square pick-off prism is optimally positioned close to the internal filter wheel, supporting the use of guide cameras with large sensors, while preventing any vignetting of the main sensor even with very fast optical systems.
