Zoe J. ★★★★★ Oct 22, 2026

Installed this on my ASI174 and the difference in image clarity is immediate—no more dust specks showing up in every frame. The fit was perfect and it threads on smoothly with no fuss. Exactly what I needed to keep the sensor clean during humid nights.

Finally got around to swapping the factory window on my astro camera for this IR-cut version. The thread fit was perfect, no slop, and it sealed tight against the sensor. First night out showed noticeably cleaner star halos on the moon.

Installed this window on my ASI174 and the sensor is completely sealed now—no more worrying about humidity during long imaging sessions. The IR-cut coating does its job without adding any noticeable tint to my frames.
