When Pixel 5 and Pixel 4a 5G were launched, they supported astrophotography through ultra-wide-angle lenses. However, after the Google Camera update, this feature is no longer supported.
according to 9to5Google, The Google Camera 8.1 update launched in mid-November cancelled the function of using ultra-wide-angle lenses for astrophotography. Previously, when switching to the astrophotography function, users could switch between .6x, 1x and 2x. Since the update, the .6x option is no longer available, and Google support documentation says that astrophotography is only available for zoom settings equal to or greater than 1x.
It is unclear why this option was removed, but whatever the reason, it is disappointing. The feature may no longer be available because its quality does not meet Google’s standards, but this is just a guess. Google can easily solve the problem by publishing an explanation.
Pixel 5 and Pixel 4a 5G owners can still use the ultra-wide-angle lens for Night Sight, but not for capturing stars. It makes sense to use an ultra-wide-angle lens for astrophotography because it allows users to capture more scenes. But users will have to use a normal lens, which still provides a relatively wide field of view.
Such as 9to5Google Note that you can uninstall the Google Camera update and revert to version 7.6, allowing Pixel 5 and Pixel 4a 5G owners to use ultra-wide-angle lenses for astrophotography. That is the version that Pixel 5 actually launched.

With winter storms sweeping across the United States, now may not be the best time for astrophotography. However, it seems frustrating to strip features from the Google flagship for no reason. Users on Reddit must have noticed.
Maybe Google Camera will be updated in the near future and re-enable the feature. Currently, astrophotographers can use zoom settings equal to or greater than 1x.
