2 inch O-III Filter greatly enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; astrophotographic 2inch filter allows high-contrast imaging even in areas with strong light pollution
Especially useful for large aperture telescopes through which the light of the Moon can be extremely overwhelming; allow just for the double Ionized Oxygen lines between 496nm to 501nm to pass through at 95 percent
Completely blocks virtually all other visible wavelengths of light so views of nebulas are optimized; increases contrast through selective filtration-Anti-reflection coated to prevent glaring and ghosting
Astromania SWA 70 Degree Eyepieces with ED Optics: Astromania eyepieces provide a high contrast image at all times the built-in ED element making this possible; the 70 degree wide angle optics mean you always enjoy a huge field of view
ED Element High-contrast Optics: The first time you observe an object through one of these eyepieces; you will almost certainly be struck by the brilliance clarity and depth of colour in the image
