Artesky 30 µm artificial star with brightness adjustment (SKU: ART-STAR)

Artesky 30 µm artificial star with brightness adjustment (Artesky, SKU: ART-STAR) creates a point-like light source for telescope collimation and image checks outside a night-time observing session. Supply adjustment changes the point brightness, while a photographic thread makes positioning it on a stable base easier.

The required source distance depends on the telescope and test. For evaluating spherical aberration, the manufacturer recommends a much longer distance, approximately at least the aperture in millimetres divided by three, expressed in metres. Extension tubes may be needed to focus on a nearby source.

The artificial star prepares and checks a telescope without waiting for a bright star at night.
