Customer Reviews (4.6 / 5 · 5 reviews)

Hazel ★★★★★

Swapping this in on my FSQ-106EDX4 tightened up the stars in the corners noticeably compared to my previous setup. The 0.73x reduction is spot-on for getting wider fields without losing too much resolution. Took about five minutes to thread on and collimate.

Eva ★★★★★

I was worried about back focus with my FSQ-106EDX4, but the 0.73x reducer threaded on smoothly and gave me crisp stars across the full frame. The image circle is noticeably flatter now in my wide-field shots.

Madison S. ★★★★★

The 0.73x reduction on my FSQ-106EDX4 really opened up the field for wider nebulae shots without any noticeable star distortion at the edges. Took a bit of fiddling to get the back focus right, but the crisp results were worth it.
