However, for this, you need a star. Unfortunately, a real star is often unavailable due to poor weather conditions or location. \u003c\/p\u003e \u003cp\u003eBut even if a star were available, you would need a good tracking system because the star is constantly moving. Air turbulence can also affect your tests. Furthermore, the real star might not even reveal the true optical quality of your telescopes, preventing perfect collimation. \u003c\/p\u003e \u003cp\u003eAn artificial star is an excellent alternative to a real star. With an artificial star, star tests can be performed precisely at any time and anywhere. The problem with an artificial star, however, is that you need a star size suitable for your telescope and the respective focal ratio. A suitable star size is also necessary for different lighting conditions and different distances between the telescope and the artificial star. \u003c\/p\u003e \u003cp\u003eThe \u003ci\u003eHubble 5-Star\u003c\/i\u003e artificial star is the perfect solution to this problem. \u003cb\u003eIt has 5 bright white LEDs with 5 precision pinholes\u003c\/b\u003e (50\/100\/150\/200\/250 microns).
