OCAL Electronic Collimator Software v4.5 Update Notes

OCAL Electronic Collimator Software v4.5 is a major update. The core improvement is a greatly simplified operating logic, with frequently used functions from previous versions fully integrated into the main home screen for fast access, even for first‑time users.

Update Contents

1 Essential controls moved to the home screen
Brightness, gain, focus, and digital zoom are now available directly on the main interface, eliminating the need to 

navigate through submenus for faster, more intuitive adjustment.

2 Improved centering code input
The centering calibration function is now integrated into the home screen. Decimal‑based algorithms have been removed, replaced with separate X‑ and Y‑axis input. Values take effect immediately, and can be saved for future use.

3 Streamlined “More Settings” menu
Only non‑essential parameters remain, such as saturation, gamma, and color temperature, reducing menu complexity and avoiding interference with core collimation tasks.

4 New 3‑vane spider support button
Added dedicated support for 3‑vane secondary mirror spiders, expanding compatibility with more telescope designs.
Customizable interface layout

5 The software and video display are now fully integrated, supporting manual drag‑and‑drop resizing and aspect ratio adjustment for a personalized workflow.

In addition, the product manual for OCAL v4.0 has been fully revised for improved readability and clarity, making learning and operation much more efficient.
