At all working distances, green laser beam is especially at dark working fields, green laser pointer is especially bright and visible at night. As a result, once users are in need to make stargazing at quite long distances, this kind of laser device can always make great work. Usually users can selects quite low powered Class IIIa 5mW green laser pointer to make stargazing. It is not only very safe, but also making great result for celestial objects observation. Even though 5mW green laser is not as visible as expected, however, this safe used astronomy laser pointer is always making great work in all kinds of astronomy observation work.
Sometimes astronomers would like to make clear and accurate targeting of a certain star or constellation in the sky. As a result, astronomy green laser pointer might not be used separately, but using together with astronomy telescope. According to simple mounting on telescope, green laser pointer will project a highly bright and visible green laser beam. It is parallel with the tube of telescope. On basis of the good result of good alignment performance, users only need of make proper adjustment of laser beam targeting direction, thus always bringing users the most satisfied astronomy stargazing result efficiently.
When users want to make stargazing with astronomy laser pointer at night, users should always be cautious enough with powerful laser beam positioning. Users should not try to stare at powerful green laser beam directly. For the most important of all, users should never try to point powerful green laser beam to air plane, vehicle, eye and bodies of human and animals. Only if users are clearly know enough about laser safety rules, astronomy green laser pointer can always bring users the most satisfied observation result efficiently.
