Give your telescope setup more room above the tripod. The Dark Clear Skies ASCENT 200 is a 200mm tripod pier extension compatible with ZWO AM3, AM3N, AM5, AM5N and AM7 mounts. It connects directly to the ZWO TC40 tripod and features an open four-pillar design, circular mounting plates and a black finish.
Positioned between a compatible tripod and mount, a pier extension raises the mounting position to create additional space around the tripod head. This can help with clearance for a long telescope tube, diagonal or imaging accessories as the telescope moves across the sky.

A practical addition to your observing or imaging rig
- 200mm extension: adds height at the tripod head where your setup needs extra clearance.
- Open four-pillar construction: keeps the central fixing area accessible during assembly.
- Multiple mounting holes and slots: the photographs show the actual plate layouts so you can check the connection required for your equipment.
- Raised circular adapter: supplied in the configuration pictured.
- Black finish: with engraved ASCENT 200 and Dark Clear Skies branding.
- Fitting hardware supplied: includes the screws, washers, thumbscrews, locating post and hex keys shown.
