5d: Collimation Using a 2nd Telescope

updated: 2024-04-17


In the final stage of the process, the telescope's optics are refined using a real or artificial star. This enables the stars to appear as points again, rather than as distorted or elongated blobs.

Previous Step

Step 4: Check and correct Mirror Distance

Next Step

Gear Installation an Calibration (Northern Hemisphere)

Collimation using an artificial star involves placing an artificial star at the focal plane of a second telescope and turning that telescope towards the telescope you want to collimate. The second telescope will act as a collimation lens for the artificial star and provide a collimated beam, like a real star at infinity.
