Telescope Alignment Evaluation Image_Labeled.png

Star field with central star NASA/STScI While the intent of this image was to focus on the bright star at the center for continued calibration, Webb's optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up. At this stage of Webb’s mirror alignment known as “fine phasing” each of the primary mirror segments have been adjusted to produce one unified image of the same star using only the NIRCam instrument. This image of the star with the catalog number of 2MASS J17554042+6551277 has been colorized using a red filter to optimize visual contrast.
