Thanks Paul & Jim for your insights. Seems like this is just another variation on music at star parties. Some folks like it, some don't. The pointer would be appropriate for an outreach-type, public education star-party, scouting event, etc., but should probably be kept under wraps during dark-sky, "serious" (whatever that means) viewing or imaging sessions, club "dark of the moon" nights. In 1997, when I was going-out every clear night (and morning!) to shoot comet Hale-Bopp (images for the gallery coming SOON!), my biggest annoyance was airplanes. One-fourth of my frames were marred by jets passing-through the field; since my eye was glued to the narrow field of the guiding eyepiece for all of the 3-to-5 minuite exposures, I never noticed them until I had the rolls processed. Nothing can be done about jets, but if I had found several green laser "trails" on those exposures, there's a good chance I would have had a confrontation with the wielder.
