The ToupTek G3M678M Planetary Mono is a 1.25" barrel size planetary camera using the Sony IMX678M CMOS sensor. With a quantum efficiency of >83%, read noise as low as 0.42e- and 2.0µm pixels, the G3M678M is an excellent camera for high resolution lunar and solar imaging with shorter focal length telescopes.

The G3M678M's back-illuminated sensor has a large resolution of 8.3 megapixels, QE up to 83% and very good NIR sensitivity, making it possible to use IR-pass filters to cut through the atmosphere and bring out finer details.

Note: in order to attach 1.25" filters to Touptek G3M series planetary cameras, you must use the included 1.25" barrel extender. The standard CS adapter does not have the necessary M28.5 filter threads.

The G3M678M is equipped with USB 3.0 connectivity as well as a traditional ST-4 autoguiding interface. Thanks to the high transmission speed of USB 3, the G3M678M can reach a fast 47FPS at its full 8.3MP resolution. The built-in 512MB DDR3 memory ensures reliability over long sequences of high framerate video capture. Its 1.25" barrel design also makes it straightforward to use with most off-axis guiders (OAG not included).

Available in anodized Red.
