Engineers said they have managed to fully focus the $10 billion observatory on a test star. The name of the star is MASS J17554042+6551277. I am sure astronomers have reasoning behind the name. The super sharp performance is described as phenomenal. The 18 mirrors were aligned to tiny fractions of the width of a human hair. A lot remains to be done before the telescope can be put to full time duty but off to a great start.
