IC,
Suggest you find an astro club and talk to some members about lasers - ideally during an observing night - before wasting your money to buy one.
While they are useful to point out objects in the sky to a group of people e.g. during a public night with a large group of onlookers, as a finder device for more serious use with a telescope they are not such a good idea.
In particular using a star party you will rarely find anyone with a telescope using them because there are better finders available - starting with the red-dot finders, TelRad, or even old-school 8 x 50 finderscope. All beat lasers hands-down IMHO.
And those with a scope properly set up with encoders (or GOTO) and integrated with SkyFi and an iPad or Android running "Sky Safari pro" (or similar) quite simply do not need pointers at all.
Many here have made the mistake of buying a laser, only to find it lies unused in the box most nights.
