Customer Reviews (4.6 / 5 · 5 reviews)

Lily F. ★★★★★

The promixal detail on solar surface popped like I'd never seen before once I added this second filter to my 40mm setup. Threading it on was straightforward and the lock ring held firm through a full session. Worth every penny for the contrast boost.

Leo B. ★★★★★

I was worried about getting the threads to line up correctly, but the front-mounted design clicked right into place on my Lunt 40mm. The double stack really tightens up the Ha detail; I could see surface granulation clearly on my first morning out.

Edward ★★★★★

The double stack threading was seamless—it locked onto my 40mm scope in under a minute, no wobble at all. First look at the sun and the surface detail just popped, way crisper than the single stack ever gave me. Solid purchase for anyone who's already got the base scope and wants that extra contrast
