Abigail I. ★★★★★

Finally got this installed on my rig and the difference in my nebula shots is night and day — the narrow 3nm bandwidth really blocks out all the light pollution I’ve been fighting. I was able to capture the Veil Nebula with structure I’ve never seen before from my backyard.

David ★★★★★

The 656.3nm wavelength cuts through light pollution perfectly, finally revealing the Veil Nebula in my images. I had to dial in the focus carefully, but the contrast on the hydrogen regions is incredible. This filter made my narrowband setup feel complete.

Eli P. ★★★★★

Waited for clear skies to test this on the Orion Nebula, and the 656.3nm bandpass really made the hydrogen detail pop out. My subs have noticeably more contrast than with the wider filter I was using before.
