Filtre Bloquant Lunt B1200 en Renvoi Coudé 2” – Spécifications et caractéristiques

Visit Lunt B1200 blocking filter, intégré dans un renvoi coudé au format 2”, est spécialement conçu pour l’observation et l’imagerie solaire dans la raie Calcium-K (Ca-K), centrée sur la longueur d’onde de 393,4 nm. Ce filtre offre une bande passante étroite (<2,4 Å), idéale pour révéler les détails subtils de la photosphère et de la supergranulation solaire. Avec un diamètre généreux de 12 mm, il est optimisé pour des télescopes ayant une focale allant jusqu’à 1080 mm, rendant cet accessoire parfait pour les astronomes solaires exigeants.

Why observe in Calcium-K?

La raie Calcium-K met en lumière les zones magnétiques intenses de la photosphère et de la chromosphère solaire. Ces longueurs d’onde permettent d’observer des phénomènes tels que :

  • Facular beaches : Bright regions associated with magnetic fields.
  • Solar granulation: Bubbles of hot plasma on the Sun's surface.
  • Sunspots: Dark areas surrounded by shadows.

Bien que cette raie soit difficilement perceptible à l’œil humain (surtout avec l’âge), elle est parfaitement détectable par les caméras modernes, ce qui en fait un outil idéal pour l’astrophotographie avancée.

Key features

  • Blocking filter diameter : 12 mm (B1200), optimisé pour des focales jusqu’à 1080 mm.
  • Renvoi coudé intégré : Format 2”, compatible avec les porte-oculaires 2”.
  • Multiple connections :
    • Entrée au coulant 2” pour le porte-oculaire.
    • 1.25" outlet with integrated T2 thread for camera or eyepiece.
  • Narrow bandwidth : <2.4 Å, centered on the Calcium-K line (393.4 nm).
  • Maximum safety : Conforme aux normes internationales pour l’observation solaire sans risque.
  • Robust construction: Machined aluminum case with high-precision optical components.

Pourquoi choisir le filtre bloquant Lunt B1200 en renvoi coudé 2” ?

  1. Advanced visual observation and imaging : The B1200 offers a field of view suitable for telescopes with moderate focal lengths, and is ideally suited to modern sensors.
  2. Outstanding image quality : Thanks to its narrow bandwidth, it guarantees sharp, high-contrast images without light interference.
  3. Total safety : Effectively blocks harmful UV and IR radiation, ensuring safe use for your eyes and equipment.
  4. Universal compatibility : Fonctionne avec tous les télescopes solaires Lunt équipés d’un porte-oculaire 2”.
  5. Versatile design : Ideal for solar imaging thanks to its integrated T2 thread.

Recommended applications

  • Limited visual observation in Calcium-K : For those able to perceive this wavelength (especially after cataract surgery).
  • Advanced solar astrophotography : Compatible with modern cameras equipped with medium and large sensors.
  • Idéal pour des focales allant jusqu’à 1080 mm : On intermediate instruments.

Included in the package

  • Filtre bloquant Lunt B1200 intégré dans un renvoi coudé 2”.
  • Adapter for 1.25" eyepieces.
  • Detailed user manual.

Compatibility

The B1200 blocking filter is designed for use with :

  • Lunt solar telescopes or any system compatible with Calcium-K.
  • Standard 1.25" or 2" eyepieces.
  • Modern astrophotographic cameras with T2 threads.

Important

The B1200 blocking filter must be used exclusively with a telescope or system equipped with a Lunt Solar Systems Calcium-K module. It cannot be used alone or as an independent accessory on an instrument not dedicated to solar observation.
