Unlock the full potential of your Seestar. Say goodbye to image rotation and hello to crystal-clear deep-sky shots with longer exposure times In EQ mode with the ZWO Seestar EQ Polar Wedge!

The Seestar S30, Seestar S30 pro and S50 are revolutionary, but their standard Alt-Az setup has one enemy: field rotation. With the ZWO TH10 Polar Wedge transform your smart telescope into a Equatorial (parallactic) mount. This is the official ZWO solution to make professional astrophotography accessible to all.
Why this Seestar EQ Polar wedge is the ultimate upgrade:
- Equatorial Mode (EQ): Tilt your Seestar exactly at the correct latitude (up to 90°). This will make your telescope follow the stars in a natural arc, allowing you to extend exposure times to 30 or even 60 seconds without streaks or black edges.
- Perfect Compatibility: Specially designed for the entire Seestar family. Fully compatible with the Seestar S50, the Seestar S30 and the new Seestar S30 Pro.
- Ultra-smooth alignment: Thanks to the hydraulic damping system and precision scaling, you set the telescope on the Pole Star with extreme accuracy. No more fussing with extending tripod legs to get level.
- Rock solid & compact: Made of high-quality CNC-machined aluminum. Despite its light weight of only 411g, this head effortlessly carries up to 5kg, ideal for the stability needed in astrophotography.
How this EQ Polar wedge works for the Seestar
Place the TH10 between your tripod and your Seestar. Use the built-in protractor to set the head to the latitude of your location (approx. 52° for the Netherlands/Belgium). Activate the “Equatorial Mode” in the Seestar app and see how your stacks instantly get more detail, less noise and a perfectly round field of view.

I can now take great photos at 30 and 60 seconds. I couldn't do that before.
