Askar M54 Off-Axis Guider (OAG) and adapters
L'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: adapters for connecting to your optical tube
The telescope side of the OAG connects directly to the optical tube (the main part of the telescope) using adapters with different thread sizes, corresponding to the most common dimensions in astronomy.
- M42 telescope adapter This adapter is designed for telescopes or accessories with 42 mm (M42) threads. If your telescope has an M42 thread, this adapter enables you to attach the OAG stably to your optical tube.
- M48 telescope adapter This second adapter is designed for 48 mm (M48) threads, a size often used for slightly larger accessories. If your telescope uses an M48 thread, this adapter ensures a suitable connection.
Note In addition to these adapters, the OAG is equipped with a front seal M54. This gasket is a kind of additional ring that reinforces the tightness of the connection between the telescope and the OAG. By using this gasket, you minimize light leakage and stabilize the whole assembly for greater guiding precision.
Camera side: adapters for connecting to your camera
On the camera side, OAG also offers several adapters to fit the different threads commonly found on astronomical cameras. This allows the camera to be securely fixed to the OAG, ensuring precise guidance with no risk of misalignment.
- M42 camera adapter Designed for cameras with M42 threads, this adapter provides a direct, secure connection between the OAG and the camera.
- M48 camera adapter If your camera has an M48 thread, this adapter fits perfectly and offers optimum compatibility with larger sensors.
- M54 camera adapter For cameras with a 54 mm thread, this wider adapter provides a solid, stable connection, ideal for configurations requiring a more robust attachment.
Why adapters are important
These adapters enable the OAG to be adjusted to fit perfectly between telescope and camera, regardless of thread dimensions. By using the right adapter, you ensure a stable, watertight connection, which is crucial for avoiding offsets and achieving precise guidance.
Summary
In short, the adapters supplied with theAskar 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.
