Thanks Andrea, that makes sense now looking at the grating colors and the Fraunhofer Lines. 

One  question, So are the lines always a constant with Sunlight?

The wavelengths of the Fraunhofer-lines are constant and are sometimes used as references.

For calibrating spectrometers wavelength calibration lamps are often used.

The peaks or lines from exited gases are also very constant and known with many decimals length.

Here is list for Argon lines:

Thanks for the info ulf

Nate, I owe you an apology for not asking first whether I could play with your truck photo.

I liked/like that truck and didn't think!

Admins are not above the rules!

@Andrea B.All good, I didn't even think any lines were crossed. You can, or anyone are free to make anything I upload better. I'm open to all pathways of better editing or someone's personal preference. The way I think about it is, the more I learn, the better photographer I'll be.

These are really nice images @Nate. I like the blue-violet. You do a great job shooting out of the ordinary subjects. It is interesting to see different things in IR and UV.

 

Thanks for sharing,

Doug A

Thanks @Doug A I'm itching to get out and shoot, weather is so crappy now here.
