Model: zapstar
This artificial star provides a dependable, steady and stable reference for precise star collimation. It's very bright 18,000mcd ultra white led focused on a 100 micron precision laser drilled stainless steel aperture produces beautiful diffraction rings when defocused in any eyepiece.
The placement of the star depends on the telescope. For an 8" SCT we recommend approximately 100 feet. The further away from the scope, the better, until you lose contrast in the eyepiece. Indoor use is a possibility though it is better to collimate the scope when it is in its usual position.
