Warning: Meade White-Light Solar Filters are only intended for closed tube telescopes and should not be used with open truss designs such as the Meade 10, 12 and 16” LightBridge Dobsonians. Incident sunlight allowed in by the open tube design could cause damage to the telescope optics and on these designs will cause instant and irreversible eye damage potentially including permanent blindness. A light shroud is not sufficient protection from harmful solar rays.
