Artificial Star - RGB (Red/Green/Blue) - For Telescope Collimation and Testing
Artificial stars allow you to collimate a telescope perfectly without having to wait for a perfect night. A particular advantage is the possibility to reduce or even eliminate the distracting influence of atmospheric turbulence by setting the star and the telescope up inside a closed room.
No Need For Night-Time Telescope Collimation Anymore
It almost sounds too good to be true, but this is exactly what you get with the Optik Star. This device is not a simple home-made device. It has a very precise and small 50 micron hole.
Specifications:
- high precision artificial star with 50 micron diameter
- sturdy housing with separate on-off switches for Red, Green and Blue
- easy to set up (on a wall or a tripod)
Composite RGB Light
The Optik Star RGB allows you to star-test your telescope in the three separate colours (R - Red / G - Green / B - Blue). This allows you to judge the focus difference between the separate colours in your refractor telescope, as well as the optical correction of your telescope in each of these wavelengths. When switching on all three colours at the same time you get a white light for "conventional" testing.
