The “Star Eater” problem is a form of software spatial filtering designed to reduce noise in photos, particularly hot pixels. Unfortunately, the rather rudimentary filtering algorithm that Sony is using easily mistakes sharp pinpoint stars for noise, deleting them from the image or greatly reducing their brightness. The result is an astrophoto with less stars and the appearance of diminished resolution.

By signing this, help sony users who love astrophotography to have opportunity to shoot milky way without disappearing stars due to sony's forced firmware update.
