TS-Optics Newtonian Laser Collimator - 1.25"

With the TS Newtonian adjustment laser the exact collimation of your Newton telescope succeeds in a few minutes.

  • Sturdy, safe all-metal construction - no plastic parts!
  • The laser diode is adjustable, should the laser ever take a blow.
  • Comfortable 45° view
  • Long 1.25" barrel with wide base for a precise hold in the focuser
  • Convenient on/off button

The advantages of the TS LA:

  • Rigid all-metal design. Once collimated, the laser will not lose its collimation. Not a simple plastic unit!
  • The laser diode can be recollimated should it get a shock.
  • Comfortable 45° side viewing port
  • Long 1.25" barrel and broad flange for perfect position of the laser inside the focuser of the telescope
  • Handy on/off button

A significant improvement - the 45° view port of the laser:

The 45° angled view port allows you to see the collimation progress from the rear of the telescope. Even large Newtonians can thus be easily collimated by a single person.

Using the laser collimator in fast Newtonian telescopes:

Fast Newtonian telescopes usually have a secondary mirror offset. This means that the secondary mirror is not perfectly in the center, but a few millimeters away from the focuser and towards the primary mirror. The offset is used so that the telescope illuminates the field of view more evenly. This offset makes collimation with classical collimation eyepieces (like a Cheshire) difficult. A laser collimator does not have any problem with offset, so collimation is much easier with the laser.

How to use the TS laser collimator:

Step 1: Preparation
We recommend to turn the telescope so that the focuser will face up. Then you insert the laser into the 1.25" receptacle or 1.25" reducerwithout using the locking screws of your focuser. The laser will then sit on its CNC machined edge and you will achive a higher accuracy.
Step 2: Collimation of the secondary mirror
Bring the laser dot to the center of the primary mirror by using the collimation screws of the secondary mirror unit. A central mark in the middle of the primary mirror (see third image) is helpful.
Step 3: Primary mirror collimation
Turn the laser collimator so that you can see inside the 45° angled view port from the rear end of the telescope (already possible at step 1). Then use the primary mirror collimation screws until the returning laser dot hits the center of the laser.
Finished! Now your Newtonian is properly collimated and ready for a successful and joyful night of observing!
