Among all types of visible laser devices, green laser pointer is always projecting the most visible and the most easily absorbed green laser light source through a middle wavelength of 532nm. Among all visible optical spectrum, it gets the most sensitive color green laser beam to human eyes, once it is used as an astronomy observing laser device, it is also getting good use for both of astronomer and astronomy enthusiasts.

In process of star pointing and positioning work, 1mW and 5mW green laser pointer always project highly visible green laser beam an green laser spot at several miles far away, thus it can be used for constellation and celestial body identification. astronomy enthusiasts can use it to point highly bright and visible green laser beam to specific constellations or celestial bodies in the sky, helping them and others to quickly and accurately find and identify targets, facilitating in-depth research of all astronomy information.

Owing to its ultra compact size and pen style design, this 532nm green laser pointer is also working together with a telescope positioning assistance. When using a telescope for observation, first point the star pointer to the target celestial body, and then adjust the telescope, which can more conveniently include the target in the telescope's field of view and improve observation efficiency. When this green laser pen projects highly visible green laser beam of about 2 kilometers far away, it can help star observers to make longer distance stargazing as expected.

In those of astronomy explanation and communication, this highly visible beam emitting device of 532nm green laser pointer is used as an assist in astronomy information explanations. It is helping a lot for those of astronomical science activities. It is allowing the audience to more intuitively understand the celestial position and constellation characteristics described by the explainer, and increase the fun and effect of popular science.

In all kinds of stargazing communication works, when all astronomy enthusiasts are observing together, they can use this Class IIIa 5mW green laser pointer to point out interesting celestial bodies or phenomena they have discovered to their companions clearly. It is making it even more convenient to exchange research experiences with each other.
owing to its extremely clear and visible green laser light emission in the night sky, this 532nm green laser pen can be clearly seen even in an environment with a certain amount of light pollution, which is conducive to accurately indicating targets in the vast sky. When it is not in need to make stargazing, it should be put into its case where child cannot reach easily.
