Red-shift compensation?

TiffsAndAstro:

I had a crazy thought the other day.

Has anyone ever played around with correcting the RGB channels of an image to compensate for red-shift?

Sometimes I get bored and come up with weird ideas.

are amateurs even capable of taking images of stuff so distant that red shift is an issue? 
 using NB Ha filter, the shift would move it outside of the filters bandpass so it would be blocked anyhow?

Still an interesting question though.

Actually I worked in Space Command for 10 years working on hyper-spectral satellite systems. I didn't mean my question to sound like an amateur. I was just keeping it casual.

I'm talking about something like an image taken by an RGB camera, but in post, adjusting the colors to represent their true wavelength based on the red-shift. I left filters out since the filters can't account for red-shift, plus the bandpass for each channel would have to be pretty generous so the light we want doesn't get filtered out. The filters would be more of a hindrance than helpful. Capturing the light without a filter would give any adjustments to the channels ample room so nothing gets lost.

The challenge is finding a target that can be captured that is far enough away, but not too far. The rest is simple math to calculate the red-shift and adjusting the channels accordingly.
