Capture Sharper Deep-Sky Images with the OGMA OAG Off-Axis Guider
This OAG is a professional-grade off-axis guider designed for astrophotographers seeking zero flexure, lightweight guiding, and ultra-low profile integration with your telescope and camera setup. Unlike bulky guide scopes, this OAG uses a precision-engineered prism to divert starlight to your guide camera, eliminating differential flexure errors during long-exposure astrophotography.
Key Features & Benefits:

  • ✅ Ultra-Low Profile Design: Saves backfocus (only 17.5mm) for compatibility with field flatteners, reducers, and DSLR/mirrorless cameras.
  • ✅ Prism Adjustments: Easily align the prism to avoid shadowing the main camera sensor.
  • ✅ Zero Flexure Guarantee: CNC-machined aluminum construction ensures rigidity for pixel-perfect guiding accuracy.
  • ✅ Broad Compatibility: Works with ZWO ASI, QHY, and other guide cameras (1.25” nosepiece included).
