Wow - what a great image.
It is hard to know how good it is unless compared with a previous image.
I assume these old images are from Hubble?

It's obviously much better than the images above.

I would like to know a lot more about it:
Which colours were mapped to which infrared wavelengths?
How many exposures?
What was the length of time of each exposure?

It's a pity that JWST uses a triple armed cradle to hold the secondary
as the six main diffraction spikes - and many more - it makes are annoying.



cheers
