Vespera Dual Band Filter
Reveal the hidden structure of nebulae.
The Vespera Dual Band Filter is a narrowband interference filter that keeps only the two wavelengths nebulae shine in. The result: higher contrast, finer details and sharper stars, from the city or under a dark sky.
Why the Dual Band filter
Only the light that matters.
Two wavelengths, nothing else.
It isolates Hydrogen Alpha (656.3 nm) and Oxygen III (500.7 nm), with a 12 nm bandwidth on each, and blocks the rest of the spectrum.
Works under any sky.
Because it rejects almost everything but these two emission lines, it improves your images in a light polluted city as much as in the countryside.
Full aperture, full quality.
Designed by our engineers for Vespera's optics, it is used at full aperture, with no loss of optical diameter.
Vespera adapts to it.
An electronic micro card in the lens ring lets Vespera detect the filter and adjust its observation and image processing settings.
Example targets
A few targets among many.
Some well known objects, one per family, where the Dual Band filter excels. The list is not exhaustive: the filter works on many other emission nebulae, planetary nebulae and supernova remnants.

Well-finished filter that does its job perfectly
Very easy to install, Vaonis vespera pro 2 recognise it straight away! Solar filter means I could use my telescope day time…dual band lens makes my astrophotography images of deep sky objects more detailed, CLS filter helps in city
Finally got some clear nights to test the equipment. It perform perfectly as expected. I wish that the apt would download in my windows laptop and could not find any reference.

J ai eu l occasion de tester le filtre Dual Ban dqns la soirée du 14 octobre la seule avec un ciel parfait tres pur
J ai choisi comme cible la nebuleuse Pacman..filtre tres facile a insfaller .
L initialisation se passe toujours tres bien
Le resultat apres 2 heures de pose
Le resultat n est pas mal du tout pour moi
Je joins deux photos .1 la photo brute et2 apres une petite utilsation de sky color
L echelle de pollution lumineuse ici est de 6
Il faut que je me cache un peu de certains lampadaires qui sont tres genants
Je vai tester aussi quand le ciel le permettra le filtre cls que j ai egalement reçu
Ici l eclairage public ne s etaint qu a 1h du matin jusqu a 6h
Malgré cette pollution lumineuse mais en navigant entre les maisons et quelques arbres je pense que je vais arriver quand meme a de bon resultats avec ce vespera 3 et ses filres.qui sont vraiment xuper.tout est OK
Es una maravilla, sobre todo, para los que no somos expertos en astrofografía.
Cada noche deseo tener cielos despejados para poder seguir aprendiendo con el Telescopio Vaonis Vespera Pro 2 y los filtros.
Ce filtre est incontournable pour libérer le potentiel de votre smart télescope.
Le gain en détails est saisissant. Installé en un instant, ce filtre fait des merveilles sur les nébuleuses par émission et en milieu urbain : le fond du ciel devient bien sombre et les extensions gazeuses ressortent magnifiquement.
Si vous hésitiez en raison du tarif, allez-y les yeux fermés, le résultat est au rendez-vous.
In a nutshell
- Ideal for nebula photography
- Increases the contrast between the sky background and the stellar object
- Refines stars and details
