Deep-sky photography needs a long exposure time, while the long exposure time will need precise guiding to make sure the image quality. The long time tracking of the Astro-objects will cause the object to leave the monitor view slowly because of the systematical error, including the mechanical system and the temperature change as well as the atmosphere reflection. The guiding camera is to improve the tracking.SV905C guiding camera is a sensitive and high-speed color astronomy camera for planetary imaging, lunar and solar imaging, and some bright deep space objects imaging. This camera is also great for ‘lucky imaging’ of planets, double stars, and other compact objects, especially for telescopes with longer focal lengths.
