$100 a bit pricy


Approx €76 incl. carriage for a 30+mW laser sounds very reasonable to me. :?

I'm confused by the wattages on green lasers.

Atlasnova have their astronomy lasers at $79. On their website they are listed as Class IIIa lasers which means they must be below 5mW.

I can understand how better manufacturing could yield a better beam, but not how it can magically increase the wattage sixfold and still be Class IIIa.
