SkyWatcher’s Star Adventurer Tripod Extension gives you a column extension to mount accessories 21.59cm (8.5″) higher, without sacrificing the tripod’s stability. This can be very helpful when you’re trying to do your polar alignment with your Star Adventurer mount. You can mount anything with a 3/8″ connection and use it with any tripod that also has a 3/8″ bolt: like the Star Adventurer Tripod.
