Filter holder with Dew Shield for ZWO Seestar S50 2"

Dew is often a problem on clear nights. After a short time, the optics start to fog up, making observation or photography impossible. A good dew cap reduces the risk of fogging and thus extends the observation time.It also keeps out stray light from the side. Stray light, for example from street lamps, reduces contrast and often causes unwanted reflections in photographs. A protective cap prevents stray light from entering the telescope in the first place.
