This handy artificial star emits a bright fibre optic light in RGB (Red, Green & Blue) light that emulates a star in the night sky. You can then use this for collimating refractor telescopes even when it's cloudy.
A high quality made padded case to suit 9.25", 10" & 11" SCT telescope tubes. Makes transporting your scope easy and safe. This will ensure your scope stays in collimation whilst protecting your precious optics.
