The QBP (Quad Band Pass) filter is a specialized narrowband filter designed to selectively transmit SII, Ha, OIII, and Hb wavelengths. With its relatively wider bandpass, it is ideal for astrophotography and observing emission nebulae. Made from high-purity fused quartz glass, this filter ensures excellent transmission, including UV wavelengths, while offering minimal contamination and high heat resistance. It is M48 mounted and crafted with precision in Japan.
