Obviously the AAA isn't a 'ruling' body but that misconception may not be all bad. It possibly gives amateur astronomers some respect that a (perceived) 'ratbag' like myself would not receive and so may have helped make the legislation less draconian.
Unfortunately on the issue of necessary laser power they are wrong, or at least not completely correct. I have a 5mW mounted on my dobs and it is fine for pointing the scope under reasonable skies. It is even barely adequate in my light-polluted back yard. I also have a 30mW and it's use is a public viewing nights where there are lights shining from buildings, a major road nearby and a full moon. Thge 5mW would be lost there but with the 30 I can point out Crux or Scorpio etc to a small group and they can all see clearly. [Naturally the pointer is either in my hand or in my pocket. It is never left lying about.] I would not use the 30 under dark skies as it affects dark adaption too much and washes out the sky.
Judging from other posts I think other members here would agree with my assessmant. I have no idea how to contact AAA but if anyone could have a word in the appropriate ear it would be appreciated.
