VAONIS Dual Band Filter for Vespera (AC022)

The Vespera Dual Band Filter is a dual narrowband interference filter that will significantly improve your photo quality whether you are viewing from an urban or natural environment.By selecting very precisely the wavelengths of Hydrogen Alpha (H-alpha) and Oxygen III (O-III), found mainly in nebulae, the filter will increase the contrast between the Stellar object and the sky background Thus, its use makes it possible to obtain a higher-quality image, with sharper stars and finer details.Significantly improves photo qualityIdeal for nebula photographyIncreases the contrast between the sky background and the stellar objectRefines stars and detailsA filter specifically studied for VesperaThe optical quality of the Dual Band filter has been specifically studied by vaonis engineers to offer use at full aperture, without any impact o The lens ring is equipped with an electronic micro-card that allows Vespera to detect the Dual Band filter and adapt its observation and image processing parameters.Transmission curveThe filter features 12nm of bandwidth in each wavelength (O-III = 500.7nm, H-alpha = 656.3nm).InstructionsDesigned specifically for Vespera, the filter fits easily and discreetly into the optical arm Remove the standard Vespera lens ring and insert the Dual Band filter until you hear a click To verify that the Dual Band filter is properly positioned, connect Vespera to your mobile device and launch the Singularity app
