The imaging camera I have used up to the point of purchasing the QSI683wsg is the Orion Starshoot Pro V2. This is a one shot colour cooled CCD camera incorporating a large Sony Super HAD-
This allows for a decent FOV even when married to the native focal length (3040mm)of the LX200. I also use an Optec Lepus focal reducer to provide F6.2 and an increased field when required. This reducer does not apply any flattening which is necessary for ACF (Advanced Coma Free) optics which already have a reasonably flat field.
A recent purchase is this ZW Optical ASI120MM camera. This is a monochrome camera capable of very high frame rates and uses a hightly sensitive CMOS chip. Due to the small pixel size the focal length needed is only about two thirds of the focal length needed for the DFK in order to achieve the same image scale. In order to produce colour images it is necessary to shoot separate captures through red, green and blue filters. These images are then combined to produce a full colour image during the processing stages. Overall this is more work but ultimately due to the lack of a bayer matrix on the chip, more sensitivity is achieved and this results in improved image quality.
The QSI683wsg monochrome CCD camera is a recent purchase and a step up from the Orion in terms of imaging capability & quality. The camera uses a full-
