The Seestar S50 comes with three built-in filters: a UV/IR Cut filter, a dark field filter, and a dual narrowband light pollution filter (bandwidth OIII 30nm/Hα 20nm). The dark field filter switches adaptively. You can manually activate the dual narrowband light pollution filter in the Seestar app. When you start shooting, the dark field filter will automatically engage, while the UV/IR Cut filter remains permanently active. For certain deep-sky targets, bright stars, or situations with strong light pollution, the dual narrowband filter should be enabled—in other scenarios, you can manually turn it off. Regarding the automatic prompts for enabling or disabling this feature, I will take note and provide feedback
