H-alpha Filter: The H-alpha filter allows light with a wavelength of 656nm to pass through. It is considered the best option for narrowband H-alpha astrophotography when aiming for high-contrast images and revealing intricate nebula details, even in areas affected by strong light pollution. OIII Filter: The narrowband O-III 3nm filter is specifically designed for observing nebulae. It allows a narrow 3nm bandwidth of light centered at a wavelength of 500nm, which matches the OIII emission lines, while blocking all other wavelengths. SII Filter: The narrowband S-II 7nm filter transmits light at a wavelength of 672nm with a 3nm bandpass, making it ideal for nebula photography.
