I'd like to know if they can identify what has made those Einstein rings?
We know they are galaxies but what type?
They couldn't be from spiral galaxies as they are so old there shouldn't have been any such galaxies then,
They must have been very early irregular galaxies that have been smeared out into rings?
Could some of them be Quasars?
Still - I don't know why they used triple struts to hold the secondary mirror
instead of the 4 struts as Hubble used?
The triple struts are creating more diffraction spikes.

If they are the curved elements you mean , I think I read on the NASA web site some form part of a circular galaxy and the showed this by identical spectra.

This article says - (about 1/4 of the way down the many pages) -
that one of those galaxies is a spiral type and it's image is also repeated:

Looks like I have an answer from another forum.
If you look at this picture from the link above here:
The Hexagon mirrors are already giving 6 strange spikes with multiple copies
of the hexagon shape of the many mirrors.
The struts they use are overlapping that pattern.
This is a great video which answered many of my questions from - Scott Manley:
New Space Telescope Images Show That It's a Game Changer - JWST Reveals First Images

My take on the images released by the JWST earlier this week,
a whole new level of detail is now possible with this new instrument.
Moreover, I wanted to answer some questions about what we're seeing in the images,
and, why the stars have 8 points while Hubble images only show 4.
I looked back on some old data from 2014.
This was a tiny crop taken out of the picture with an 8" Newt and my QHY-9 mono
in RGBL and Ha.
It looks awful but that's all there is of a similar field of view.
At the risk of stating the obvious to the community (many of whom I am sure already know this), I thought I would let people know that you can download ALL of the JWST raw scientific imagery and data free of charge from the MAST Portal (Barbara A. Mikulski Archive for Space Telescopes), and then play with it to your heart's content. (Maybe you'll discover something knew to science in the gigabytes of JWST data as it is uploaded and shared?) Note that the data from a whole bunch of space telescopes, including Hubble, TESS, etc is available from the MAST Portal, not just JWST.
Create an account on the "My Space Telescope" website https://proper.stsci.edu/proper/authentication/auth (I'm not sure if this step is strictly necessary, but it seemed to be necessary on my computer to activate the "Download Manager" on the MAST Portal)
Filter for the target you are interested in, and the space telescope that captured the data you want to inspect - e.g. enter "WASP 96-B" into the search bar, and then after it loads up the available data list, check the "JWST" filter to just see the Webb data
Select the dataset(s) you want to download (by instrument and filter, etc) and "Add to Download Basket" - I would strongly suggest that you do NOT just click "Download" - you might have selected literally hundreds of gigabytes of data!
View your "Download Basket", and filter it to get a manageable set of files to download (FITS image files, CSV tabular data, etc)
Press "Download", and when your download has completed, "Extract" all files into suitable User folders
hi guys - i downloaded some of the calibration stuff from Webb - they were testing the scope's ability to track objects which move.
was hoping there were more of jupiter in there (there are few more but not of the whole planet (some sneaking in view or featureless due to the filter).
nice to see NASA deal with some internal reflections too
