I am wanting to get a laser powerful enough to do astronomy presentations with groups of 15-20. We could say the group will make a 20' radius. I need them to see something of the beam as they are beginners. What mW is recommended?

Hmmm... I know it is subjective but I wonder what people mean when they say the laser is really bright in their reviews. I would call this laser mostly dim :(

At first no but I put in fresh Duracel brand and it did get a little brighter. Seems like the 30mW would be brighter based on what I have read and the videos I watched in my research. Again... just a few feet away to the side and it is gone.

I purchased a 35mW laser and it seems weak to me. I was expecting to be able to star gaze and have others see the beam? If you are sighted right in the beam is visable to the one operating the laser but get just a few feet away to the side and it disappears. I live in a rural area so not much...
