ZWO OAG Off-Axis Guider

Product Description

The ZWO OAG Off-Axis Guider is an off-axis guiding accessory designed for astrophotography setups that require accurate guiding during long-exposure imaging. Instead of using a separate guide scope, the OAG uses a small portion of the main telescope's light path to provide a guiding signal to a compatible guide camera.

This design helps eliminate differential flexure between a guide scope and the main imaging telescope. As a result, the guide camera and imaging camera track the same optical system, which can help maintain accurate star positioning during long exposures.

The ZWO OAG features a compact design with adjustable guide-camera positioning, allowing users to find suitable guide stars within the available field of view. It is particularly useful for deep-sky imaging with longer focal-length telescopes, where precise guiding is important.

The OAG can be integrated with compatible ZWO cameras, filter wheels, filter drawers, and other imaging accessories to create a flexible astrophotography imaging train.

FAQs

What is the ZWO OAG used for?

The ZWO OAG is used for off-axis guiding by sending a small portion of the main telescope's light to a guide camera.

Does an OAG require a separate guide scope?

No. An OAG uses the main telescope's optical path, so a separate guide scope is not required.

What is the advantage of off-axis guiding?

It helps reduce differential flexure because the guide camera and imaging camera use the same telescope and optical system.

What size is the OAG prism?

The ZWO OAG uses an 8 × 8 mm prism for picking up guide stars from the telescope's light path.

Is the ZWO OAG suitable for long-exposure astrophotography?

Yes. It is particularly useful for deep-sky imaging with longer exposures and longer focal-length telescopes where accurate guiding is important.
