This custom 3D-printed fine-focus mechanism is designed to provide greater precision when adjusting your telescope’s focus. It achieves a 4:1 reduction ratio by converting a 60-tooth gear motion into a finely tuned 15-tooth output, allowing for smoother and more exact focus control, especially during astrophotography sessions or detailed celestial observations.

Compatibility & Testing:
This model has been successfully tested on the Uranum Estelar 150mm x 750mm (F5) telescope, proving its effectiveness in delivering enhanced focusing capabilities. Its modular design ensures compatibility with a range of telescopes, making it a valuable addition to any amateur astronomer’s toolkit.
