If you want a laser pointer that will meet your astronomy goals, the htpow green laser pointer is a very solid choice. Once you decide which laser to use, you must follow our laser pointer safety tips. Since some of the bright objects in the sky may be planes, a circle has to be made instead of a point. Instead of simply pointing the laser directly at what you think the star is, surround the star - this will keep the beam moving and avoid lingering on the underlying plane. Even a 5mW laser can pose a serious danger to pilots from miles away.
You may notice this is a "shotgun laser". Is it different from a laser pointer? Well, no. But with so many regulations already in place, you will no longer find laser pointers for sale on a big site like Amazon because of the word "pointer". The term means you're pointing it out to someone, so you're more likely to see a "pen" or just a simple "laser". There are still some of the larger laser pointer companies in stock, but for the most part, when you see laser pointers, you'll find people talking about smaller mW pens or those for presentations.
Power output
Laser pointers vary in many ways, but power remains the most important consideration. Higher power levels, measured in milliwatts (mW), produce more energetic beams. They are easier to reach than their low-powered counterparts and can sometimes trigger matches when pointed directly at them. For most simple tasks, these high power laser pointers are not a safe choice.
The low output power can still generate enough energy to irradiate the high power laser pointer spot across the room. They require less mass to operate and produce fewer milliwatts than more powerful laser pointers.
Color Laser
While red lasers are still the most commonly used in homes, blue and green laser pointers are growing in popularity. These alternating laser colors have higher power levels and can be used for remote activities. Green laser pointers are best for astronomy applications, and red laser pointers handle many everyday tasks.
