Artificial stars for telescope collimation.
This useful accessory produces a uniform star with a small diameter using glass fibre. This "star" can be used to check the telescope’s collimation even during the daytime.
In the RGB version of this accessory, there are even three coloured stars available, so that the collimation for these three colours can be checked.
