Vaonis Dual Band Filter for Vespera

Vaonis Dual Band Filter for Vespera

The Vespera Dual Band Filter is a narrow-band interference filter that significantly improves the quality of your images, whether you are photographing in the city or in nature.

By precisely selecting the wavelengths of hydrogen alpha (H-alpha) and oxygen III (O-III), which are mainly found in nebulae, the filter increases the contrast between the star object and the sky background. This results in a better image quality with sharper stars and finer details.

Features:

• Improves the photo quality 
• Ideal for nebula photography 
• Increases the contrast between the sky background and the star object 
• Refines stars and details 
• The dual-band filter only allows two specific wavelengths to pass through to the Vespera sensor: O-III and H-alpha 
• Can be used at full aperture 
• The objective ring is equipped with an electronic microcard that allows Vespera to recognise the dual-band filter and adjust its observation and image processing parameters 
• The filter has a bandwidth of 12 nm at each wavelength (O-III = 500.7 nm, H-alpha = 656.3 nm)
