Réducteur/Correcteur (0,85x) pour Evostar 100 (S20201)

The star field in my recent test shot from the Evostar 100 looks noticeably flatter at the edges than my old setup, and the .85x reduction lets me fit the full Pleiades cluster on my sensor. It threaded on smoothly and didn't shift focus during the session, which is all I really ask for.

The reduction ratio is exactly .85x as promised, which noticeably widened my field of view on the Evostar 100 without distorting stars in the corners. One night of imaging showed much tighter star shapes compared to shooting without it.

I mounted this reducer on my Evostar 100 and immediately noticed the correction across the entire frame—no more bloated stars at the edges. It threaded on smoothly and cut my exposure times by about 30%, making those faint nebulae pop in less than two hours.
