Learn How to Polar Align the Astro Tracker
The Slik ECH-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 ECH-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 ECH-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 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.
Check out our blog here on the ECH-630 to see how you will use the built-in peep holes to align the tracker to Polaris or any other celestial body.
