OK thanks and the filters are explained here:
https://jwst-docs.stsci.edu/jwst-nea...nircam-filters


Also - exposure time:
https://www.bbc.com/news/science-environment-62122859

Hubble used to stare at the sky for weeks on end to produce this kind of result.
Webb identified its super-deep objects after only 12.5 hours of observations.


Also - I checked out the RA and DEC on Stellarium
but it didn't come up with anything I could identify.

R.A. Position 07:23:19.5 Dec. Position -73:27:15.6

A good point, and I agree with you. However, I get the impression that the description was pitched at the general public to try and give people a broad sense of the capability of the Webb.


In any event...I'm impressed with what the Webb can do! I look forward to seeing many more images from the Webb. We live in an exciting time.

There's a nice comparison of Hubble Deep Field vs Webb First Deep Field here:

The additional detail and resolution is astounding!

I stayed up late to watch the first images.



They are here on flickr:
https://www.flickr.com/photos/nasawe...h/52211883534/


They are magnificent pictures:
I especially like part of Eta Carinae shown here:
https://www.flickr.com/photos/nasawe.../in/datetaken/


And Stephan’s Quintet:

Sheesh!...some years ago I did a fun comparison with HST, just to see what features I had nabbed in my data, of almost this exact section of Gabby...the JW result is totally mind blowing!

I think JWST is trolling me there are very few example images that show the outer shells of NGC 3132.

But man! Look at the level of detail in the JWST version! (make sure you click on the image twice) iiiiiiiincedible!

No wonder I couldn't find it.
I was looking at close to the Keyhole Nebula.
Why didn't they say that it was Gabriela Mistral nebula in Eta Carinae ?


cheers
