Need help with equipment.

[ben.]

I once read an article at my friends house about some photography equipment but I don't remember the name of it. Here is what I remember of it:
- It allowed to increase the shutter speed up to 30 minutes (even longer if desired)
- Some photographer used it in the night and the picture showed the path that the stars took.
- It held the lenses open (and didnt let them close) up to the point where you choose to close them.

Anyone knows what I am talking about??

Help would be greatly appreciated.

Bulb mode on your camera, use a remote shutter release to make it easier/better.

could you explain further what to do to get it and how much i should look at ($ money wise) ??

no need to post this in two different areas, check your other thread about the same subject.

but again, just dial the shutter control down to bulb. continue to hold the shutter down, best done with a cable release cable which is something you may need to buy. Release the shutter when the time is up. Don't forget the tripod.
