By selecting with great precision the wavelengths of Hydrogen Alpha (H-alpha) and Oxygen III (O-III), which are mainly found in nebulae, the filter will increase the contrast between the stellar object and the celestial background. Thus, its use allows a higher quality image to be obtained, with sharper stars and finer details.
Keep only the essentials
The dual-band filter is designed to allow only two specific wavelengths to pass the Vespera sensor:
- O-III
- H-alpha
Due to the filtered wavelengths, it is especially effective for photographing emission nebulae (e.g. Orion nebula M42, Heart nebula IC 1805...), dark nebulae endowed with hydrogen (e. g. e.g.: Horsehead or Elephant trunk nebula...), planetary nebulae (e.g.: Owl nebula M97, Dumbbell nebula M27...), supernova remnants (e.g.: Veil nebula, Crab nebula M1...).
For globular clusters (e.g.: Hercules cluster M13, cluster M92...), the selectivity of the dual-band filter will help you to obtain sharper stars.
A filter specifically designed for Vespera VAONIS
The optical quality of the Dual Band filter has been specifically studied by our engineers to offer a 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.
Transmission curve
The filter has a bandwidth of 12 nm at each wavelength (O-III = 500.7 nm, H-alpha = 656.3 nm).
