Slik Astra ECH-630 Astro-Tracker
The SLIK ASTRA ECH-630 Astro-Tracker is a compact motorized turn table with speed settings for star, moon, and time-lapse photography. Some astro-tracking heads can weigh up to 5kg but the ECH-630 weighs just 630g 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 ECH-630 capacity varies based on its angle. It can hold up 5kg when the turntable is flat and up to 2kg at a 90 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 ECH-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.
