| the beam is much more visible from a pusar if it is being pointed at you or near you. (which i know is a big no no around here) |

yes, any laser is more visible when pointed towards you.

I didn't really expect the pulsar to be that bright at night. I just bought it for the Mw

Is it correct that at night, once our eyes ajust to pitch black we can see further into the IR spectrum than we can during the day?
If so then I think that if we went into a room at night, switched the 650nm laser on, it would seem bright, but if we stayed in pitch black for say 30 minutes and then switched the laser on again, the laser would seem much brighter than normal?
Just a theory...

This may assist you with your question:
The following pictures are of the 100mW Pulsar MK1 which was actually outputting closer to 125mW. As you can see, the beam can be seen in dimly lit rooms but only when there's a little atmosphere. Outside, it is ideal for Starpointing and the dot is much brighter when compared with a 5mW red pointer. If you light an incense candle, you will see the beam in a lit room as a faint, thick , cherry-red beam with a translucent appearance. If you add smoke from a Fog Machine (even a cheapie), the beam becomes VERY apparent and looks absolutely spectacular. I've said this before but about 15 years ago, a 10mW red laser was a 3 foot tube costing over $5,000.00... so to have one that fits in my shirt pocket yet exceeds 100mW is extraordinary considering the price.
Alongside some Greenies from Wicked. Note the thicker and more translucent beam.
Outdoors during a thunderstorm (yes, that's rain which helps illuminate the beam).
TThe Red showcased alongside a Blue Spyder and a green Elite Laser with a $50 Fog Machine and a home-built mirror system.
Yes, you can use the Reds of this output for Starpointing but note that a 15mW beam would be more visible to the user in the night sky. But the advantages of Reds are:
* a lower cost per mW output.
* a constant-on beam with no cycle times.
* an excellent visible laser in smoked environments.
* suitable for hobbyists/laserists as a collection piece.
* suitable for scientific demonstration or lectures (NOT as a pointer!).
Remember thought that the ouput of this laser makes it worthy of respect due to the hazards associated with Class3B lasers.
These Reds can in some instances (and with suitable materials) cut through thin plastic with ease. Be sure to avoid reflected and specular light from these classes of lasers.
