SV220 1.25" or 2" Dual-Band Nebula 7nm Filter telescope guiding camera 7x Reducer for ASKAR 107PHQSVBONY SV220 Dual Band Filter SVBONY 7nm dual band filter is designed to drastically reduce the effect of light pollution. The 7nm bandwidth means it strongly isolates the nebulae's emissions into H Alpha (red) and OIII (green blue) from anything else. It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background. It also blocks artificial light from mercury vapor lamps, high and low pressure sodium vapor lights, and
