    It’s not that bad. At the red to NIR end of the spectrum it should have considerably better resolution than the Hubble. It’s only when you get to MWIR and LWIR that you start losing resolution.

      Months now for it to cool down-
      I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-

          That is quite amazing. The screen resolution on my 16" MacBook Pro is 3072 x 1920, and the JWST in the final frames occupies one moving pixel. I wondered what sort of telescope was used, and found this in the comments.
          .
          The photos were shot with a $1,799 Celestron RASA 8 telescope, a $999 ZWO ASI183MM Pro monochrome camera, a $2,268 iOptron CEM40 equatorial mount, and an Astronomik H-alpha 12nm filter

            Yeah, seeing what he has done really reminds me I need to get my scope out and test the mount I made.

              Webb is now in its "halo orbit" around the L2 point.

                Why does it need to orbit the L2 point? What (forces) is it orbiting? Can't it "just" orbit the sun synchronously with Earth?

                    I am glad you were able to answer your own question! Your link with its amazing simulation is way beyond anything I imagined.

                      All the more amazing is that much of the orbital mechanics involved was figured out in the 1700's. ...makes me feel even more stupid!
