Self Barlow inzetstuk voor alle holografische lasercollimatoren

Self-barlowed attachment - Now collimate even more precisely

Now collimate your Newtonian telescope even more precisely with the help of this self-barlowed attachment. Simply screw it into the thread of your Howie Glatter laser and you will no longer see a more simple point, but a diffuse beam.

The reflection makes it more accurate

You see the rear projection of the main mirror marking on the white surface of the self-barlowed attachment. Now set your primary mirror even more accurately, until the collimation is perfect.
