Roughly speaking sure, but the color mapping function they used just paints the longest wavelength the telescope can see “red” and the shortest “violet”. No attempt is made to properly “undo” redshifting.
I’ve been unable to find any technical reports on the technique, but the gist of it is here: https://www.axios.com/2022/07/17/james-webb-space-telescope-nasa-photos-processing https://www.axios.com/2022/07/17/james-webb-space-telescope-...
- heavenlyblue 4y agoIt does seem like the redshift would need to be fixed on a star-by-star basis depending on how far away is the star.
- falseprofit 4y agoI think you mean galaxy-by-galaxy.
