Actually, that is not good. A high power red becomes a dangerous object, and looking at the dot on a wall, as well as stray hit can cause eye damage. If your purpose is astronomy, its best to go with a 10-15mw Greenie. Having a higher power laser pointer is not always a good thing, unless you want an all in one.
Thats what I am suggesting :p

If you want one for the sole purpose of stargazing, then a 5mW 532nm Greenie will do
