Just a small thing to remember

When experimenting with two DSE webcams, especially when they are two different video qualities, make sure you keep the lenses straight. 
I had decided to use the 640x480 webcam for astrophotography, so I put the CIF resolution one back together.  Should have tested it first, because it turns out there is a difference in their lenses.  Oops. (sheepish grin)
