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 light-polluted skies. This narrow-band filter blocks almost all artificial light and only allows the emission line of ionized sulfur at 672 nm to pass, revealing details invisible without the filter. It greatly enhances the contrast of deep-sky objects, especially for astrophotographers and urban observers. A must-have for any amateur astronomer, this filter ensures quality results thanks to its individual test certificate.
