SOLOMARK 2 INCH NARROWBAND OXYGEN-III O-III NEBULA EYEPIECE IN SOUTH AFRICA

Solomark 2 Inch Narrowband Oxygen-III O-III Nebula Eyepiece Filter The SOLOMARK O-III 10nm filter significantally enhances the contrast of planetary and gas nebulae, thus allowing observation of faint objects even in the suburbs of bigger cities. How does the SOLOMARK O-III filter work? Countless lights from urban sources reduce the possibilities of astronomical observation. The SOLOMARK O-III 10nm Filter blinds out these parts of the spectrum and lets the wavelengths of O-III and H-alpha light pass. So it enhances the contrast of these objects in relation to the background. For which objects is this filter suitable? The SOLOMARK O-III 10nm filter is especially designed for diffuse and planetary nebulae. Famous objects like the Dumbbell, Cirrus and North America Nebula can be observed much better. The observation of minour nebulae is often only possible by using an O-III filter. For which telescopes is this filter suitable? We recommend this filter for all kinds of telescopes with an aperture of 90mm and bigger. It is easily screwed into the filter thread of an 1.25 eyepiece. Package Include: 1 X 2 inch O-lll Filter 1 X Sturdy plastic case
