Narrowband filters represent a significant advancement in performance and durability for imaging and research purposes. These filters enhance the contrast of emission targets by reducing background signals, ensuring a guaranteed transmittance of over 90% at the emission wavelength. This high transmittance provides the strongest possible signal for astrophotography. Additionally, narrowband filters are designed to minimize halos around bright stars, even during long exposures of 30-45 minutes, which are common in narrowband imaging.
