iOptron Mini Pier CEM40/GEM45/HAE43/HEM44

iOptron MiniPier for CEM40, GEM45, HAE43, and HEM44 Mounts – #8031

If you've ever wished for a little more clearance between your telescope and tripod legs—especially when observing near the zenith or using longer optical tubes—the iOptron MiniPier offers a simple and highly effective solution. This rugged, lightweight extension pier is designed specifically for the CEM40, GEM45, HAE43, and HEM44 mount heads and increases vertical clearance without compromising stability or portability.

Add Elevation, Avoid Interference

At 6 inches tall and 4.8 inches (120mm) in diameter, the MiniPier raises your mount head just enough to prevent longer OTAs from striking the tripod or spreader tray during low-altitude slews or meridian flips. It’s an ideal upgrade for:

• Refractors with long focal lengths

• Imaging setups with rear-heavy payloads

• Observers using binoviewers, diagonals, or extended dew shields

Adding the MiniPier helps protect your gear while maintaining access to the full range of mount motion—no awkward tube collisions or lost targets near the zenith.

Durable, Lightweight Construction

The pier is built from die-cast and CNC-machined metal, delivering strength where it counts while keeping weight to a minimum. At just 1 lb 4 oz (567 grams), it adds almost no burden to your overall setup—but makes a big difference in functionality.

Compatible Mounts and Tripods

The #8031 MiniPier is designed to mount directly to:

• iOptron CEM40

• iOptron GEM45

• iOptron HAE43

• iOptron HEM44

It fits securely atop the following iOptron tripods and piers:

• iEQ30 tripod

• CEM40/GEM45 tripod

• Carbon Fiber Tripod (#8061)

• iOptron Tri-Pier

Important Compatibility Note:
This MiniPier does not fit the iOptron iEQ45, CEM60, MiniTower, or AZ Mount Pro tripods.

Observing Tip:

If you're imaging with a rear-heavy refractor or using a large diagonal, the MiniPier can help reduce the risk of OTA/tripod collisions during meridian flips—especially when guiding unattended. It’s a small upgrade that can save you from a night-ending crash.

Final Thoughts

The iOptron #8031 MiniPier is a simple, effective way to improve clearance and operational safety when using longer OTAs on your CEM40, GEM45, HAE43, or HEM44 mount. It installs quickly, travels light, and blends seamlessly with your existing iOptron hardware—making it one of the most useful accessories you didn’t know you needed.
