Google Camera 8.1 for Pixel 5 and Pixel 4a 5G Quietly Disabled Astrophotography Mode With Ultra-Wide Lens

Google has not clarified as to why the Astrophotography feature does not work with Pixel 5 and Pixel 4a 5G's ultra-wide lens, though it was presumably due to the overall quality. The Astrophotography shot is available under the Night Sight tab on the Google Camera app.
