About this product

Model:  astdym_m54_tilt_adjuster
Part Number:  M54-TILT-ADJUSTER

These rotating tilt adjusters compensate for tilt in your imaging train when using any threaded adapter or extension tube.

The adapter only needs to be partially unthreaded to allow the tilter to rotate to the area that needs to be compensated for.

Each tilt adjuster adds 0.40mm ± 0.03 of back focus.

 

Each set comes with 3 levels of adjustment: 0.1, 0.2, and 0.3mm, and the corresponding amount is debossed onto the adjuster itself with roman numerals.

These are meant for correcting large amounts of tilt. For reference: aluminium foil is 0.016 mm thick.

  • I = 0.1mm
  • II = 0.2mm
  • III = 0.3mm

How does it work?

A raised section on each adjuster acts as a shim, which pushes one side of a threaded adapter higher than the other, this is the mechanism that creates the tilt effect.

The maximum amount of compensation that can be produced is dependent on the tolerance of the threads (how much slop they have).

For example, ZWO's extension tubes (16.5 & 21mm) have been tested to produce a maximum of 0.20mm worth of tilt.
