Player One S-Series SHO 7 nm filters

Player One S-Series Hα / S II / O III 7 nm narrowband filter set - Format 1.25″

The narrowband filter set Player One S-Series SHO 7 nm combines the three essential filters for monochrome astrophotography: Hα (Hydrogen-alpha), S II (Sulfur-II) and O III (Oxygen-III). Designed with high-quality optical substrate and a multi-layer composite coating technologyThese filters offer high transmission, excellent out-of-band cut-off and optimal halo control, guaranteeing sharp, high-contrast images even on faint objects.

With a half-value width (FWHM) of 7 nm ± 0.5 nmThese lenses precisely isolate the wavelengths required, while effectively blocking light pollution and spurious emissions. Ideal for imaging deep-sky nebulae, this set delivers fine detail and a richly nuanced Hubble palette (SHO).

Technical specifications

Highlights

• High optical performance High-quality optical glass and multi-coating for maximum contrast.
• High transmission (~90 %) : effectively captures Hα, S II and O III emissions for fine detail.
• Optimum blocking OD3 out-of-band cut-off and IR cut-off to avoid spectral contamination.
• Halo control Artifact reduction around bright stars.
• FWHM 7 nm The ideal compromise between rejecting light pollution and capturing weak signals.
• Universal compatibility M28.5 × 0.6 thread for all standard 1.25″ filter holders and drawers.

Applications

• Emitting nebulae Precise capture of Hα (656.3 nm), S II (672.4 nm) and O III (500.7 nm) lines.
• SHO imaging (Hubble palette) channel composition for spectacular false-color images.
• Reducing light pollution improves contrast even under urban skies.
