Off-Axis Guider from Nanjing AMADA Instrument.

Products

All products in this category

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

Advantages

  • 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

FAQ

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.
