Newton Telescope Laser collimator 1.25 Inch

Hi,

I did not want to spend so much money on a bought laser collimator for my newton telescope…

Here is a simple two part collimator. You need a cheap 6 mm laser module, 6 M3 screws and thats it… The plane areas at the top are just for you to mount whtaever you need there - I put a DC converter there, but you maybe will want to also put a battery pack there…

As the cheap laser modules are incredibly inaccurate (direction), You can adjust the position (bottom three screws) and direction of the beam (top 3 screws). 

The drawback of this collimator is, that you cannot see the alignemnt while you are turning the screws from the main mirror - you will need to watch through the front and align the returning beam in a way that it goes hits the middle of the collimator.

Thats it :)

Printing: Standing, laserout down for both parts, no supports. if you use “bright” colors, you can see the laser at the bottom, even if you dont have it aligned - this simplifies alignment of the laserpart in the main part.
