Original manufacturer description below.
The collimation problem of the reflecting telescope is a problem that astronomers must solve. The OCAL electronic collimator is an electronic device developed by Chaoxing Astronomy to calibrate the collimation of reflective telescopes. Its main function is to mark several calibration circles through software to achieve the purpose of collimation.
The OCAL electronic calibrator has the following features:
- Each Collimator has perfect pixel level accuracy in our high quality control.
- Installing the collimator by M42 threads minimizes the install error.
- The collimation errors may cause by different visual axis of human eyes in the traditional collimation tools. It can be total eliminated by OCAL.
- The product can solve the problem of collimating large telescopes, with the assistance of collimation result shows on screen immediately.
- 4 steps collimation by this product. It is easy and suitable for everyone.
- You can share your collimation result by screenshot. Or sending your collimation screenshot to us to get technical support.
- Compared with the 2.0 optical axis calibrator, the OCAL3.0 electronic optical axis calibrator has a greater breakthrough in hardware.
OCAL3.0 electronic collimator has the following three advantages over the second generation OCAL electronic collimator:
- Brand new large aperture lens and CMOS, with the same ambient brightness, the exposure time of OCAL3.0 electronic collimator is only 1/20 of the second generation electronic collimator. Now the new calibrator can be used in darker environments Adjust the telescope to be collimated.
- The clarity of the OCAL3.0 electronic collimator image has been greatly improved. Now you can see clearer primary mirror marks and more reflection information, and it still performs well when equipped with a correction mirror.
Introducing the OCAL 3.0MAX electronic collimator
Since the release of the first generation OCAL electronic collimator, it has achieved great success and has been recognized by many astronomy enthusiasts around the world. Adhering to the concept of "keeping integrity and innovation," we continue to increase investment, conduct in-depth research and development, and are committed to producing telescope collimators with higher precision. After the efforts of the first, second and third generation collimators, we specially customized the 3.0 MAX version of the electronic collimator, which is the best among all current versions. It has significant improvements in the following two aspects:
- We believe that only by minimizing the error of the collimator itself can we bring better results to the telescope collimation. Therefore, we use the best camera module assembly method in the industry, which allows the tilt error to reach a high-quality level recognized in the industry. The average tilt deviation of the 3.0 MAX camera module is expected to be <10′, which greatly reduces the error demonstrated in the figures below.

- We have also made major changes in the assembly of the camera module and metal casing. We changed the previous solution of only using screws to limit fixation to a solution of limiting slots and separating the camera module from the PCB. This solution ensures the assembly accuracy of the camera module and the housing, and the uncertainty in the strength of the screws that fix the PCB will not affect the camera.

The 3.0 MAX collimator must use the latest software version. The software operation and tutorial content have not been changed and remain consistent with version 3.0. We believe that for some telescopes with shorter focal lengths and larger focal ratios, the electronic collimator version 2.0 can already meet the needs of most customers. In order to provide a better purchasing experience for some customers who do not have high accuracy requirements, we have decided to stop sales 2.0 PC version, and the price of the 2.0 PRO version has been significantly reduced.
