Hi Glen,
Thanks for the read. I would only add that whilst the JWST mostly observes in InfraRed, according to the
JWST Technical Info, there is also
some response down in to the visible light range of 0.6µm (600nm), covering deep orange/red/Ha,
depending on which instrument it is using. As a result it doesn't have to be all false colour, unless they wish it to be.
Best
JA
