The video demonstrates the set-up of an equatorial mount designed for astrophotography. While one of the smallest and lightest equatorial mounts, the SkyWatcher EQ3 mount is easily transportable and provides excellent results when paired with an 80mm or smaller refractor. The Orion 80mm carbon fibre aprochromatic telescope in the video could be replaced with a SkyWatcher 80mm Equinox or other smaller apochromatic telescope. A similar set-up would be used with larger equatorial mounts and larger optical tubes.
