Use the Slik SMH-250 Micro Adjustment Mount in conjunction with your ECH-630 Astro Tracker to make polar aligning the tracking unit faster and more precise. This mount acts as an equatorial wedge to set your longitude during alignment, and is easier to use and more stable than using a standard ball head. Made of a lightweight aluminum and treated with an anodized finish, it weighs just 8.8 ounces and is very compact. The base of the mount is Arca-type compatible.
