It does not track the arc of the stars across the sky, which is necessary to prevent star trails in long exposures. While it is excellent for visual observing and short-exposure planetary imaging, it is not designed for deep-sky astrophotography.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion\"\u003e\n    \u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use this 400mm mount to view planets like Jupiter or Saturn?\u003c\/h3\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion-A\"\u003e\n    \u003cp\u003eAbsolutely.
