  1. Here is about 3 hours of motion of the JWST taken from my backyard in the midwest. ~~If you look closely you can actually see the curvature of the orbit.~~ Current brightness is about mag 17.2. JWST is orbiting the Sun Earth-Moon Barycenter second Lagrange point (L2). The arc is parallax cause by the motion of my telescope about the center of the earth.

    Equipment:

    * Telescope: RASA 8
    * Camera: ASI1600MM
    * Mount: HEQ5

    Acquisition:

    * 90 x 120′
    * 20 Darks
    * 20 Flats
    * gain 0 offset 10
    * Sensor temp = -20C

    Processing:

    * Calibrated in PixInsight
    * gif made in PS

  2. Really great work.

  3. Hooooooly shiiiiiiit! So awesome! Great job!

    Now if you could get the full circle, even better!

  4. Your motion tracking of JWST is amazing!

  5. According to this: [https://jwst-docs.stsci.edu/jwst-observatory-characteristics/jwst-orbit](https://jwst-docs.stsci.edu/jwst-observatory-characteristics/jwst-orbit) – it sounds like the orbital period around L2 is 6 months (which fits with [https://deepfieldfilm.com/discover/james-webbs-halo-orbit](https://deepfieldfilm.com/discover/james-webbs-halo-orbit) I think showing what seems two orbits of L2 per each orbit of the sun).

    So it would sound tricky to get much of the motion in a night – am I missing something obvious? This would not be unusual for me!

  6. Thats amazing..and yes I seen the curvature..was this last night??

    I’m new to astronomy, anyone would like to explain to me what’s JWST and L2?

  8. I was going to ask you but decided to just look it up. I had no idea the orbit diameter was 250,000 to 800,000 km around L2. I guess that would be hard to catch in a telescope haha.

  9. Really cool! I was at a space trade show in DC last week and one of the companies with a booth was the company that designed and made the decoupler that was used to separate the telescope from the rocket. Was very cool talking to them!

  10. Hard to believe it’s finally out there.

  11. Amazing you were able to locate and track it with a backyard telescope.

  12. That’s astonishing! It’s a million miles away! It’s only six metres across!

  13. I have numerous responses to a question I posed a while back that this wouldn’t be possible. Stoked that the internet was wrong, just that one time. Great post!

  14. Awesome

  15. What a shot!

  16. It’s so big but so far away it now looks tiny. Space is generally so fascinating and terrifying

  17. I love so much that dot

    Great work, mate.

  19. It’s incredible that is orbiting “nothing” Incredible.
