I take it you mean orbs of the paranormal kind. I lost a lot of pictures I took myself a few years back, days before I backed stuff up and my drive decided it was ready for the next phase and died.

Had some amazing stuff, and you dont need technical stuff to do your own research. A simple digital camera with night time capabillities will do.

Just aim it into the dark and flash away.
If you have a digital dictator recorder then why not try some E.V.P.
Can be done anywhere, I have had good results in my house and garden.

Try it its fun stuff.
