New without batteries: TS-Optics Newtonian Laser Collimator - 1.25" - precise collimation of Newtonians

TS-Optics Newtonian Laser Collimator - 1.25" - precise collimation of Newtonians

With the TS Newtonian adjustment laser, the exact collimation of your Newtonian telescope is accomplished in a few minutes. Check the collimation within seconds - you always have the guarantee to have a well adjusted telescope.

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.
