Vaonis AC022 Vespera Dual Narrow Band Interference Filter for Nebula Photography, Better Contrast and Detailed Imaging (Black Exterior)

Vespera Dual Band Filter: The Vaonis AC022 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 Application: Ideal for nebula photography Nebula: The Dual Band filter has been designed to allow only two particular wavelengths to pass through to the Vespera sensor, O-III, and H-alpha. Due to the filtered wavelengths, it is particularly effective for photographing nebulae in emission Material: Made of high-quality glass and plastic Specifically Studied for Vespera: The optical quality of the Dual Band filter has been specifically studied by our engineers to offer use at full aperture, without any impact on the optical diameter of the instrument. 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. The filter features 12nm of bandwidth in each wavelength
