LS40FHa: Double Stack for LS40THa (New standard ≤ 0.35 Å)

Double Stack 40mm filter for LS40THa

Visit Double Stack 40 mm filter is specially designed for LS40THa to significantly increase contrast in H-alpha solar observation. By adding a second standard, the system's effective bandwidth is reduced, improving spectral selectivity and revealing more detail on the Sun's surface.

Why add a Double Stack to an LS40?

• H-alpha bandwidth reduction
• Significantly increased contrast on the solar disk
• More pronounced filaments
• Better-defined active ranges

In single-standard configuration, the protuberances are luminous and spectacular. At Double Stack, The contrast of the solar disk is enhanced, highlighting fine chromospheric structures.

Compatibility

• LS40THa

The module mounts on the front of the compatible instrument and transforms your LS40 into a high-performance dual standard configuration.

Visual and imaging benefits

• Immediate improvement in overall contrast
• Better separation of fine structures
• Optimization for solar imaging
• Simple upgrading of an existing system

Key features
