Increase mount height for visual observations
If you observe visually with a long focal length refractor the eyepiece will be positioned quite low when the telescope is pointed high in the sky. With the optional Pier Extension you can easily increase the pier height with 200 mm/8inch. If you want an even higher pier more Pier Extensions can be stacked.
Extremely fast and easy
The Pier Extension attaches to the pier with the quick lock Pier adapter in a matter of seconds with the flick of a finger.
