Type 2 Plus: Made with high quality hand select glass coated with exclusive Solar II Plus. The most durable glass filter on the market. Transmission is 1/1,000th of 1% (Optical Density 5). Great for both visual and photographic use. Solar image is yellow-orange. Guaranteed fifteen years.
ARE THE FILTERS COMPLETELY SAFE? All filters, except for the lighter density photographic 3+ version, are completely safe for unlimited visual use. If handled with care and common sense, all will last a minimum of 20 years to life.
CAN THE TELESCOPE OPTICS GET HOT OR DAMAGED? No, all the heat and intense light is blocked before it can enter the telescope. Your telescope may get warm from sunlight shining on it, not from the small amount of visible light transmitted through the filter.
WHAT DETAIL IS VISIBLE? Sunspots and surface granulation are the two main features. The only detail that cannot be seen with a standard filter (commonly called white light filter) are prominence and flares which require highly specialized H-Alpha filter system.
