The Vespera Dual Band Filter is designed to improve photo quality in urban or natural settings. It enhances contrast between stellar objects and the sky background, resulting in sharper stars and finer details.
The Dual Band filter allows only two wavelengths to pass through to the Vespera sensor: O-III and H-alpha. It is particularly effective for photographing nebulae, dark nebulae, planetary nebulae, and supernova remnants.
The Dual Band filter is designed to work seamlessly with Vespera without impacting its optical diameter. It features a transmission curve with 12nm bandwidth in each wavelength (O-III 500.7nm, H-alpha 656.3nm).
The filter fits easily into the optical arm of Vespera. Connect Vespera to your mobile device to verify proper positioning. The Dual Band filter is not suitable for observing galaxies, the Moon, individual stars, or planets, and is ineffective against LED lighting.
