David ★★★★★

I’ve been struggling to get both Ha and OIII data without switching filters, but this one lets me capture them simultaneously with the galaxy’s broadband signal—total game changer for my dual-band setup. The M28.6 size fit perfectly in my filter wheel, too.

Lily ★★★★★

Finally got clear shots of the Orion Nebula with the GNB filter — the way it captures both Ha and OIII in one go is a huge time saver. The 1.25" size fits my filter wheel perfectly.

Brian Q. ★★★★★

Finally, a filter that lets me capture Ha and OIII while keeping the galaxy’s broadband signal in the near-infrared—no swapping out mid-session. The 1.25″ size fits my Canon lens adapter perfectly, and the results have noticeably sharper star shapes compared to my old dual-band.
