For the 1st photo of the tubes, here's what I used/did...
Camera: Canon Powershot SX110IS
Exposure: 15 seconds
Aperture: f/4.0
Focal Length : 9.1mm
ISO: 80
I put the camera on a 2 second timer so I wouldn't shake the camera when I pressed the button
The second shot of the front....
Same camera
Exposure: 0.125 seconds
Aperture: f/2.8
Focal Length: 6mm
ISO: 200
I did a bit of developing in iPhoto on this one....
