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.
Comentariul expertilor nostrii:
Filtrul solar se potrivește, de exemplu, la telescoapele Skywatcher N150/750, N150/1200, Omegon 150/750 EQ-3, Omegon 150/750 EQ-4 sau Skywatcher și Orion 6" Dobson. În cazul telescopelor Omegon, trebuie să scoateți inserțiile din cauciuc moale și să le înlocuiți eventual cu altele mai subțiri.
Diametrul interior al filtrului este de aproximativ 186 mm. Cu inserția din cauciuc moale, acesta este de aproximativ 182 mm.
