OCAL Electric Collimator 4.0 Upgrade your telescope alignment workflow with the OCAL Electric Collimator 4.0, designed to deliver clearer imaging, smoother operation, and more precise optical calibration. Features improved image quality with higher pixel performance and advanced CMOS technology, offering sharper detail capture and more refined visual clarity than the 3.0MAX. Uses a practical 4:3 display ratio to show the telescope’s internal optical structure more efficiently, giving users a more intuitive view during collimation. Built with the proven 3A process and high-precision assembly technology for reliable stability and consistent calibration accuracy. Smaller and lighter than previous designs, making it easier to handle while maintaining strong resistance to minor bumps and everyday movement. Finished in a bold red shell with clear exterior markings to help users quickly identify the reflective surface and operate the collimator with greater confidence. Offers an excellent balance of upgraded performance and affordability, making it a smart choice for astronomers seeking a high-value electric collimation tool.
