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:
Din pacate, descrierea acestui produs nu a fost inca tradusa in limba romana, din acest motiv veti gasi in loc o descriere in limba engleza.
The solar filter fits, e.g., Skywatcher N150/750, N150/1200, Omegon 150/750 EQ-3, Omegon 150/750 EQ-4 and Skywatcher and Orion 6" Dobsonian telescopes. With the Omegon telescopes, the sponge-rubber insert should be removed and possibly replaced with a thinner one.
The inner diameter of the filter is approx. 186mm. With the foam-rubber insert it is about 182mm.
