🆕SV220 [W9198A] 1.25-inch 3nm narrow-band filter (H-Alpha & OIII) for astrophotography

Ultra-narrow 3nm (H-Alpha & OIII) filter – Ideal for emission and planetary nebulae

This narrow-band filter uses multi-layer minimal-halo coating technology to minimise glare and halos. This significantly improves contrast and colour accuracy, renders sharp details against a dark background and optimises the purity of deep-sky images.The light pollution filter has been specially developed for full-frame sensors and is compatible with most standard astronomical cameras. It effectively reduces vignetting with ultra-wide-angle lenses, ensures uniform brightness from the edges to the centre of the image, and enables the full representation of nebulae and galaxies:

• Extremely narrow-band with a bandwidth of just 3 nm at H-Alpha and OIII – perfect for imaging emission and planetary nebulae.
• Minimal halo coating for the effective reduction of stray light and halos.
• Fully compatible with full-frame telescopes and cameras.
