Default Questions about green laser

Hello!

I'm new to this forum. I'm passionate about lasers. Now I have one extracted from a DVD recorder.
Days ago, made an order of siguirente DealExtreme module: DealExtreme: $8.81 20mW 532nm Green Laser Module (3V 11.9mm)

You think that is enough for topics of astronomy?
The beam will look good in the dark?
Anyone have any 20mw green laser to check the light emitted in the dark?

When you arrive, you'll put photos of how the model and materials used for the realization of the laser.

Thank you and sorry for my bad English.
