The OCAL 3.0MAX Electronic Collimator is a revolutionary new device for collimating reflecting telescopes with the aid of powerful and easy to use software. With the aid of precise calibration guides, the OCAL makes the daunting task of collimation a breeze.

The new 3.0MAX version has a larger aperture lens and upgraded CMOS sensor with greater sensitivity and faster FPS, allowing the OCAL to work in a wider range of lighting scenarios. Additionally, the clarity of the image has been vastly improved, making mirror marks and other reflective landmarks much easier to see.

Compared to the previous 3.0 version, the assembly of the OCAL 3.0MAX has a minimal tilting error expected to be less than 10', which it greatly reducer the error shown in the images below:

Features

High quality control ensures each Collimator has perfect pixel level accuracy.
Included M48 female adapter allows tilt-free connection to the telescope.
Supports both Windows and Android operating systems.
Collimation errors can be caused by the different visual axis of human eyes when using traditional collimation tools. This can be totally eliminated by the OCAL electronic collimator.
The OCAL electronic collimator can solve the problem of collimating large telescopes, with the real-time result shown on the screen.
The easy 4 step collimation process is suitable for beginners and experience users alike.
The OCAL electronic collimator can also check if the centre mark of the primary mirror is correct or not.
