Off-Axis Guider

Off-Axis Guider from Nanjing AMADA Instrument.

Enables simultaneous imaging and guiding through one telescope, reducing system complexity

Double helix focusing provides fine, smooth adjustment for precise guide star alignment

Enables continuous astrophotography without interrupting the main imaging path

Fixed 15″ per division reticle graduation remains unchanged across different lenses, ensuring consistent measurement reference

USB3.0 interface enables high-speed data transfer for real-time imaging and high frame rates

Compact size enables easy integration into existing microscope setups without structural modification

Auto focus with 0.01mm precision and configurable focus area for consistent imaging

Dual magnification options (0.7X and 1X) for flexible imaging across different sample types

Who this category serves

Amateur and professional astrophotographers using refractor or Newtonian telescopes
Imaging stations requiring stable, automated guiding without additional guide scopes
Users upgrading from manual guiding to automated tracking systems

Eliminates need for a separate guide scope, reducing system complexity and weight
Uses off-axis light from the main telescope for guiding, ensuring alignment with imaging path
Compact design fits standard telescope optical paths without obstructing the main beam
Compatible with standard 1.25-inch eyepiece ports on many refractor and Newtonian telescopes

What is the purpose of an off-axis guider?

It captures starlight from outside the main imaging path to guide the telescope during long exposures, ensuring accurate tracking.

Does the off-axis guider require a separate guide scope?

No. It uses light from the telescope's main optical system, eliminating the need for a separate guide scope.

Is the off-axis guider compatible with all telescopes?

It fits standard 1.25-inch eyepiece ports on refractors and Newtonians, but compatibility depends on telescope design and focal length.

Can I use the off-axis guider with a CCD or DSLR camera?

Yes. It is designed to work with standard imaging cameras connected via the telescope's optical path.

How does the off-axis guider improve image quality?

By ensuring the guiding system tracks the same star field as the main imager, reducing tracking errors and star trailing.
