The Webb - a million miles away
-
And powerful enough to detect the heat of a bumble bee as far away as the moon.
-
For the telescope to achieve a razor-sharp focus, that alignment must be fine-tuned to within 1/10,000th of the width of a human hair using multiple actuators to tilt and even change a segment's shape if required.
Oh, ok. Cool.
Puts my job's difficulty into perspective.
Can't wait for the images that come from this thing.

A picture of it at L2
Huh?
Really
Cool

How's your new home, Webb?
The image comes from a single 300-second exposure, unfiltered, remotely collected with the “Elena"" (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at the Virtual Telescope Project. The robotic telescope tracked the apparent motion of the James Webb Space Telescope (JWST), which is marked by an arrow in the center.
At the imaging time, JWST was at about 1.4 million km from us, and it had just reached its final destination, the L2 (2nd) Lagrangian point of the Earth-Sun system. As seen from the Sun, that L2 point is directly behind the Earth.
