Designed to fit snugly over the aperture of your telescope, these optical glass filters block 99.999% of incoming sunlight, allowing you to safely observe sunspots and solar granulation in the Sun's photosphere. The Sun appears in a natural, whitish color. The glass elements are machine-polished and triple-coated with nickel-chromium stainless steel for a scratch-resistant surface. Each filter has three nylon thumbscrews to ensure a snug fit to the front of your telescope or binocular. The thumbscrews complement the press-fit foam lining inside the filter's durable aluminum cell to accommodate diameters up to ﾼ" smaller than the nominal size. A tight press fit is still required for safe solar viewing. Lifetime limited warranty.
Komentarz naszego eksperta:
Filtr słoneczny pasuje np. do teleskopów Dobsona Sky-Watcher N150/750, N150/1200, Omegon 150/750 EQ-3, Omegon 150/750 EQ-4, oraz Sky-Watcher i Orion 6". W przypadku teleskopów Omegon, należy usunąć wkładkę piankowo-gumową i ewentualnie zastąpić ją cieńszą.
Średnica wewnętrzna tego filtra to około 186 mm, a z wkładką piankowo-gumową około 182 mm.
