Optical divider for off-axis guidance

Introducing the Askar M54 Off-Axis Guider (OAG)

The Askar M54 Off-Axis Guider (OAG) is supplied with a number of adapters that facilitate its integration with a variety of astronomical equipment. These adapters are designed to make the OAG compatible with a wide range of telescopes and cameras, simplifying mounting and ensuring a stable connection.

Telescope side: Lens tube connection adapters

The telescope side of the OAG connects directly to the optical tube using adapters with different thread sizes, corresponding to the most common dimensions in astronomy.

• M42 telescope adapter : Designed for telescopes or accessories with 42 mm (M42) threads. This adapter allows you to attach the OAG stably to your optical tube.
• M48 telescope adapter : Designed for 48 mm (M48) threads, it provides a suitable connection for slightly larger accessories.

Note: In addition to these adapters, the OAG is equipped with an M54 front seal, an extra ring that reinforces the watertightness of the connection between the telescope and the OAG, minimizing light leakage and stabilizing the assembly for improved guiding precision.

Camera side: Adapters for connecting to your camera

On the camera side, OAG also offers several adapters to fit the various threads common on astronomical cameras. This allows the camera to be securely fixed to the OAG, ensuring precise guidance without the risk of misalignment.

• M42 camera adapter : Designed for cameras with M42 threads, it provides a direct, secure connection between the OAG and the camera.
• M48 camera adapter : For cameras with M48 threads, this adapter offers optimum compatibility with larger sensors.
• M54 camera adapter : For cameras with a 54 mm thread, this adapter provides a solid, stable connection, ideal for configurations requiring a more robust attachment.

Importance of adapters

These adapters enable the OAG to be adjusted to fit perfectly between telescope and camera, whatever the diameter of the threads. By using the right adapter, you ensure a stable, watertight connection, crucial for avoiding offsets and obtaining precise guidance.

Summary

The adapters supplied with the Askar M54 OAG are essential to ensure flexible compatibility with different telescope and camera configurations. Whether your equipment uses M42, M48 or M54 threads, these adapters enable you to connect the OAG easily and securely, optimizing the performance of your installation.
