The S-II 1.25" 12nm filter from Explore Scientific is designed to facilitate the observation of emission nebulae, planetary nebulae, and supernova remnants, even under a sky lit by light pollution. This narrowband filter blocks almost all artificial light and only allows the emission line of ionized sulfur at 672 nm to pass through, revealing details invisible without the filter. It significantly improves the contrast of deep sky objects, especially for astrophotographers and observers in urban environments. A must for any amateur astronomer, this filter guarantees quality results thanks to its individual test certificate.
