Adam ★★★★★ Oct 22, 2026

I was worried about dust getting on the sensor during a recent humid night, but this AR window seals it perfectly and the optical clarity is noticeably good.

Benjamin V. ★★★★★ Oct 21, 2026

Installing this AR window on my ASI174MM was a breeze, and it fits perfectly flush against the sensor. The real relief is how much easier it is to keep the sensor clean compared to dealing with a separate filter.

Isabella ★★★★★ Oct 20, 2026

After fighting with dust spots on my planetary captures for months, this window screwed right on and I haven’t had to touch the sensor again. The AR coating is clearly doing its job because my flats are cleaner than ever.
