Customer Reviews (4.6 / 5 · 5 reviews)

Miles ★★★★★

The stars are round and tight right to the edge of my APS-C sensor now, which was a struggle before. It’s nice having the imaging train shortened to less than 100mm; my autofocuser no longer binds on the tube.

Charlotte ★★★★★

Put this on my 120 ED and the stars are sharp corner to corner now, no more bloated edges in my wide-field shots. The threads threaded on smoothly and the whole setup feels solid.

Hannah ★★★★★

Finally got it dialed in and the stars across the frame are perfectly round now, even at the edges. The .85x reduction really speeds up my exposures without losing that sharp APO quality.
