DIY laser collimator

[WWPierre]

Hello fellow astronomers.

I have developed a holder for the standard 14mm diameter laser pointer that turns it into a collimator. It can be made for a few bucks by anyone with access to a home workshop.

You can see detailed instructions here

Nice looking workshop!

How do you turn the laser on/off and keep it on?

Cheers

Tim

Thanks, TJ. The momentary on-off switch is positioned under the 4th screw, the one closest to the bushing.
