F107130RE Reducer

The three-element optical design gives my images a noticeably flatter field edge to edge, and the reduction from the 0.7× factor makes framing larger targets like Andromeda much easier. I’ve only used it on a few clear nights so far, but the stars look sharp all the way across my full-frame sensor.

Installed this on my FF130APO and the stars across the whole full-frame sensor are perfectly round now. The three-element optical design really pulls in extra detail without distorting the corners.

I was worried about vignetting on my full frame sensor, but this 0.7x reducer fills the corners nicely. Stars stay tight all the way to the edges now, and the three-element design really shows in how clean the field looks.
