Hey, Space Placers!
JWST is focusing!

18 separate images, one from each of the mirror segments, has now been reduced by stacking these 18 images into 1!
During this phase of alignment known as Image Stacking, individual segment images are moved so they fall precisely at the center of the field to produce one unified image instead of 18. In this image, all 18 segments are on top of each other. After future alignment steps, the image will be even sharper. Credit: NASA/STScI
