Collimation Knobs for Newton Telescope

See the product page: Order

The project

Collimation is a key step for any Newton or Dobson telescope owner. The standard screws that come with instruments are often impractical — too small, requiring a tool, sometimes abrasive against the mirror support. These 3D-printed collimation knobs solve all of these issues.

Set of 3 collimation knobs

Features

  • M4 thread, 45mm length — direct replacement for standard screws
  • 13mm diameter knob — comfortable grip, hand adjustment without tools
  • Rounded ends — prevents punching or deforming the primary mirror support
  • PETG printed — resistant to repeated handling in the field

Installation

The replacement is direct: unscrew the original screws and replace them with the knobs. No tools needed for installation or use. Perfect for observation nights in real conditions.
