The iOptron SkyGuider Series are camera mounts made for wide field astrophotography. Want to take long exposures of the Milky Way, but can't because the stars are always moving? The SkyGuider tracks the stars as they move across the night sky, allowing you to take longer exposures of the stars and the Milky Way to get more detail without having star trails in your images! The 11 lb payload capacity gives you the option to mount your DSLR with your wide angle or telephoto lens. These compact camera mounts are a must have tool for anyone interested in landscape astrophotography or wide field astrophotography.
