Color astronomical camera for astronomical imaging and compatible setups.
The color version allows colors to be recorded within a single sequence, without the sequence of RGB filters required by a monochrome camera. The choice of an additional filter depends on the target, the optics, and the model’s protective window. For short-exposure acquisitions, the effective frame rate depends on the readout mode, the selected area, and the actual data throughput provided by the computer. Pixel size must be considered in relation to the focal length and turbulence conditions. Before installation, check the threading, the distance between the sensor and the mount, and the space occupied by the filters or the optical splitter. The sensor alone does not determine the final field of view: the instrument, the focal length, and any reducers also play a role. Take your calibration images using settings consistent with those used for observations. An astronomical camera provides no protection for solar observation: any use on the Sun requires a filter specifically designed for the instrument and installed correctly.

La ZWO ASI676MC est destinée à l'imagerie planétaire, lunaire et solaire (Soleil uniquement avec un filtre adapté) par « lucky imaging » : on filme quelques minutes jusqu'à 31,2 images/s puis on empile les meilleures images. Avec des pixels de 2 µm, visez un rapport F/D d'environ f/6 à f/10 sur les planètes, avec une lentille de Barlow si nécessaire.
The Sony IMX676 is a square sensor with a resolution of 3552 × 3552 pixels and a pixel size of 2.0 µm: the square format naturally frames the Moon and Sun, and is also suitable for all-sky imaging. It has no glow and is sensitive to near-infrared light.
No: It is powered by its USB cable. No external power source is required.
The camera's back focus is 12.5 mm. Mounts: 1.25", 2", and M42 × 0.75.
Its IR-cut protective window already blocks infrared light: no additional filter is necessary. For planets low on the horizon, a ZWO ADC Atmospheric Dispersion Corrector significantly improves sharpness.
The color version is the simplest: a single exposure produces the color image. The monochrome version, the ZWO ASI676MM, requires a filter wheel and a longer exposure time. In return, it is more sensitive and produces better results in narrowband imaging.
