Use for many Cameras

The total optical draw of this optical divider is 19.5mm which makes it compatible with most of the market cameras such as ZWO camera.

You just have to make sure to get the right backfocus recommended for your corrector which is generally 55mm.


The reference distance between the edge of the DO (without the adaptive ring) and the APRINCIPALE camera sensor must be 35mm to allow a good focus of the guide camera.

With this parameter you can easily calculate the thick of the intermediate ring between the camera and the OAG if the one supplied with 18mm does not allow the map of the guide camera.

This OAG will work perfectly well with the cameras in BF of 17.5 like the famous camera from Zwo
