Monochrome astronomical camera for astronomical imaging and compatible mounts.
The monochrome version captures light without a color matrix. To create a color image, plan to take images with the appropriate filters and combine them during processing. It also allows you to work with narrowband filters depending on the target. For short-exposure acquisitions, the effective frame rate depends on the readout mode, the selected area, and the actual data throughput of the computer. Pixel size must be considered in relation to the focal length and turbulence conditions. Before assembly, check the thread, the distance between the sensor and the adapter, 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.

The ZWO ASI676MM is designed for planetary, lunar, and solar imaging (the Sun only with a suitable filter) using «lucky imaging»: you capture footage for a few minutes at up to 31.2 frames per second, then stack the best frames. With 2 µm pixels, aim for an F/D ratio of approximately f/6 to f/10 for planetary imaging, using a Barlow lens if necessary.
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.
The monochrome version is more sensitive and produces better results in narrowband, but it requires a filter wheel. The color version, the ZWO ASI676MC, produces a color image in a single exposure.
