Ellie Y. ★★★★★ Oct 21, 2026

The aluminum housing feels solid and precise, and the automatic 6-position slider clicks cleanly into each filter stop without any wobble. I've already used it for three nights of photometry, and the repeatability is spot-on.

Emma F. ★★★★★ Oct 20, 2026

It took me a minute to figure out the 6-position automatic mechanism, but once I did, it's been smooth sailing with my SSP photometer. The 12.5mm filter slots hold everything snugly and switching between positions is quick and precise.

I was a bit skeptical about the 12.5mm diameter filter fit, but it holds my filters perfectly secure and the automatic positioning is surprisingly smooth.
