The Seestar comes with three built-in filters: a UV/IR Cut filter, a dark frame filter, and a dual narrowband light pollution filter (with bandwidths of OIII 30nm/Hα 20nm). The dark frame filter switches adaptively.
You can manually turn on the dual narrowband light pollution filter within the Seestar app. When you start shooting, the dark frame filter will turn on automatically, while the UV/IR Cut filter remains on at all times.
You can manually activate the dual narrowband filter during use; for some target celestial objects, the dual narrowband filter will turn on automatically during observation.White indicates off, and red indicates on.I hope my answer is helpful to you.
