## Description

Astromania artificial Star This artificial star enables yout to test your telescope and also to adjust it perfectly. Use the valuable clear nights for working with your telescope.  The motto: never adjust in the night again - whith the Astromania artificial Star, a star for testing and adjusting is always at your hand: Here the adjustment of the telescope is much more accurately than at night, as you work in closed rooms and have no problem with air turbulence. Furthermore, it is always a problem to make use of tools in front of the optics when it´s dark. Something can be dropped too easily and then ...  Practical tip from Astromania-Service: In order to collimate a telescope or to detect optical aberrations such as astigmatism or coma you need only a short distance between the telescope and the artificial star. In these cases due to the extended focal plane you may need extension tubes in order to reach focus. Dpherical aberration is very difficult to detect using an artificial star. You should set up the star at a much greater distance from the telescope. We recommend a distance in meters that is equal to one third of the aperture in millimeters. For instance, for a telescope with 200 mm aperture you should set up the artificial star at least 66 m away from the telescope. Here we recommend using a real star.  Details: Diameter of the pinhole: 22 µm  Lighting: Neutral white (LED)  Power supply: 2x 1.5 V AA batteries (batteries are non included) Brightness: Continously dimmable and off-switch  Housing material: Aluminum Tripod connection: Photo tripod connection via 1/4" photo thread
