Pier Extension for AM3N, AM5N, AM7 Mount
The ZWO PE200 Pier Extension is designed to provide additional clearance between your telescope and tripod, helping prevent equipment collisions when imaging near the zenith or performing meridian flips. Adding 200mm (7.9") of height, it allows longer optical tubes and imaging trains to move freely while maintaining a stable, secure setup.
Built specifically for the ZWO AM3N, AM5N, and AM7 harmonic mounts, the PE200 is constructed from lightweight aircraft-grade aluminum and supports payloads up to 50kg (110 lbs). It's an ideal upgrade for astrophotographers looking to maximize clearance without sacrificing portability or stability.
