Double Stack DSII/SFPT module - Advanced solar observation

The Double Stack DSII/SFPT module is an advanced accessory designed specifically for the Lunt LS80MT and LS100MT modular telescopes. By reducing the bandwidth to < 0.5 Å, this module dramatically improves contrast and reveals exceptionally fine solar details. Complex structures, such as filaments, protuberances and chromospheric granulation, become even more visible, offering an unrivalled observing experience.

How Double Stack works scientifically

The DSII module is based on a Fabry-Perot etalon system, which acts as a high-precision optical filter. When used in Double Stack, it combines two standards to further reduce the bandwidth, isolating an even finer portion of H-alpha light (656.28 nm). This process amplifies the contrast of solar structures by eliminating stray wavelengths. The integrated tilt adjustment allows precise adjustment of the standard to optimize the image and eliminate unwanted reflections.

Key features

  • Bandwidth : Reduced to < 0.5 Å (compared with < 0.7 Å in Single Stack mode), for enhanced contrast.
  • Exclusive compatibility : Designed exclusively for Lunt LS80MT and LS100MT telescopes.
  • Tilt adjustment : Allows precise adjustment to ensure an even, glare-free image.
  • Robust construction: Made of high-quality aluminum with precision optical components.
  • Easy installation : Integrates directly into the existing LS80MT and LS100MT optical system.

Differences between LS80MT and LS100MT with DSII

With the LS80MT :

  • The Double Stack DSII module reduces bandwidth while maintaining an 80 mm opening.
  • Ideal for amateurs wishing to explore fine details on a compact solar field.

With the LS100MT :

  • Thanks to a wider 100 mm aperture, the DSII offers even greater resolution, enabling even more subtle details to be observed.
  • Recommended for astrophotographers or demanding observers looking for optimum image quality.

Why choose the DSII module?

  • Contrast enhancement : Reveal invisible solar details in Single Stack mode thanks to reduced bandwidth.
  • Advanced observation: Ideal for solar astronomy enthusiasts wishing to explore the Sun in greater depth.
  • Perfect compatibility : Designed specifically to integrate with LS80MT and LS100MT modular systems.
  • Premium optical quality: Guaranteed by Lunt Solar Systems, world leader in solar observation.

Included in the package

  • Double Stack DSII/SFPT module.
  • Detailed user manual.
  • Secure packaging to protect optics during transport.

Recommended applications

  • Observe complex structures: Like filaments, protuberances, solar flares and chromospheric granulation in exceptional detail.
  • Capture high-definition images: Thanks to optimum compatibility with astrophotography.
