The SLIK each-630 astro-tracker is a compact Motorized mount with speed settings for star, Moon, and time-lapse photography. Some astro-tracking heads can weigh up to 11 lbs. but the each-630 weighs just 22.4 oz. and takes up about the same amount of room as a 24-70mm lens in your camera bag. This makes it perfect for photographers that hike into remote locations to shoot the stars. The each-630 capacity varies based on its angle. It can hold up 11 lbs. when the turntable is flat and up to 4.4 lbs. at a 45 Degree angle. (See instructions for further details.) this makes it perfect for light-weight DSLR cameras or mirrorless cameras with fast prime lenses. 4 high-quality AA sized batteries are all that is needed for the each-630 to operate for up to 20 hours of celestial tracking, more than enough for a full night. The unit also has a Micro USB port to connect an external battery for even longer run times.
