HD 84406 - Star (JWST mirror alignment star)

HD 84406 (Ursa Major) Image taken of the star being used for the alignment and focusing of mirrors on the James Webb Space Telescope. For a few brief moments my backyard telescope was in perfect alignment with the JWST !   HD84406 was picked for JWST mirror alignment as it has no nearby stars that could confuse the operation.  The image below shows the absence of nearby stars very well.
