Baader Planetarium 20nm H-alpha Bandpass-Filters (with LPFC) Filter Size:2" In terms of visual observationWarning: this filter alone is not suitable for direct viewing of the sun! This 20nm filter replaces the former 35nm H alpha filter, which was developed for interline CCD cameras. Due to advances in sensor technology, now much narrower filters can be used with colour sensors. Compared to the CMOS optimized Baader (Ultra) Narrowband Filters, the 20 nm H alpha filter passes considerably more light. This makes the stars in the image brighter, allowing
