Our new second generation artificial star makes collimation easy. It features two star apertures: a 0–3 magnitude and a 3–5 magnitude. Each aperture is brightness adjustable. We provide a ¼–20 tripod mounting hole as well as three rubber feet if you want to set it on a table.
A USB cable to charge the internal battery as well as an external power supply that uses common AA batteries is included. On–Off power switch.
We suggest you use this artificial star with Richard Suiter's Star Testing Astronomical Telescopes.
