Using a new large aperture lens and CMOS, under the same ambient brightness, the exposure time of the OCAL3.0 electronic collimator is only 1/20 of that of the second-generation electronic collimator. If the light source is too strong, it is recommended to reduce the gain rather than simply reducing the exposure time. Now, new collimators can adjust the telescope's collimation in darker environments.

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.
