Ryan P. ★★★★★ Oct 20, 2026

Finally got pinpoint stars across the whole frame with this reducer—the edge correction is noticeably better than my previous attempts. Exposures dropped by almost half, and the image circle still covers my APS-C sensor cleanly.

Amelia ★★★★★ Oct 18, 2026

Finally got my stars looking round across the whole frame instead of just the center—that 0.85x reduction really flattens the field nicely. The threads engaged smoothly on my 72ED, no wobble at all.

Benjamin ★★★★★ Oct 18, 2026

Swapped out my old cheap reducer for this and immediately noticed sharper stars across the frame—the back focus adjustment feels precise and solid. Captures about 40% more of the nebula in a single frame now.
