What kinds of stuff can you do with a laser pointer that is astronomy related ? Do you need a certain color or power laser ? Are laser pointers capable of touching the mirrors on the moon ?
Yes, and they come in handy mainly when you're trying to show others an astronomical object. Also as sight mounted to the telescope they work well too. Just be aware of aircraft.
I use a 75mW green pointer for astronomy. Bright beam and easy to see.
