Think this is the classical image of that star, taken in visible light: http://simbad.u-strasbg.fr/simbad/sim-id?Ident=2MASS+J17554042%2B6551277&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id http://simbad.u-strasbg.fr/simbad/sim-id?Ident=2MASS+J175540... Click on fullscreen icon on right-hand side, then zoom out until FoV on bottom left says about 10.63' to 12.23'. Best I understood, that should be about the same field as the Webb image, based on the instrument definitions I read about. And I wasn't able to line up any dots visually - the new Webb image was taken with a red filter, so I thought it's likely showing photons no one's seen before. Paging any astros for corrections.

  Here’s a nice comparison baggy_trough posted below: https://twitter.com/gbrammer/status/1504369779540480002?s=21 https://twitter.com/gbrammer/status/1504369779540480002?s=21

    Wow, that's almost exactly like seeing the world when I got glasses for the first time!

    Oh god that resolution.

  Looks like it's around 2.5' and the Webb image is rotated about 15 degrees clockwise from this one. The four blobs to the left form a quadrilateral that seems to match the four bright galaxies in the Webb image. It seems like the star has moved maybe 10" downward between the two, and used to be just below that round galaxy to the left of the top spike.

  Any photon you see nobody has seen before.

    Photographs are funny like that. We can replicate once-unique information.

Or just link to the massive PNG here. Beware if your mobile plan has a bandwidth cap before clicking: https://www.nasa.gov/sites/default/files/thumbnails/image/telescope_alignment_evaluation_image_labeled.png https://www.nasa.gov/sites/default/files/thumbnails/image/te...

  Only about 5 MB compressed. Interesting to note is that even though the extension and MIME type claim it's a png, Firefox claims it's actually a jpeg. Throwing it at a couple different pieces of software, they all appear to open it with either file extension (so presumably they're going off the file header rather than the actual extension).

    File starts with 0xffd8ff, so it's a jpeg. Guess someone uploaded the wrong file.
