Isabella L. ★★★★★ Oct 21, 2026

The threads on the 1.25" adapter are buttery smooth, and the enhanced aluminum coating on the mirror gives noticeably brighter views of star clusters compared to my old prism diagonal.

Elizabeth ★★★★★ Oct 20, 2026

I noticed the 1/10th wave mirror makes stars look sharper compared to my old prism diagonal. The 2-inch barrel slid in easily without any wobble. Focused views on Jupiter this week were impressively crisp.

The 1/10th wave mirror in this diagonal gave me noticeably sharper stars compared to my old prism unit. The 2" barrel slides in smoothly with the included 1.25" adapter, making switching between eyepiece sizes effortless. For the price, this is a solid upgrade for any serious observer.
