These contrast-enhancing filters are designed to block out the wavelengths of light emitted by mercury-vapour light and other common causes of light pollution.
Progressively dims the view when observing the Moon or bright planets whilst increasing contrast, reducing glare and increasing the amount of detail to study.
The Orion Variable Polarizing eyepiece filter acts like a dimmer switch for your telescope, to tone down brightness and accentuate contrast of bright celestial objects.
This high performance CCD filter transmits only the Hydogen Beta emission line, and therefore is useful for greatly increasing the contrast of objects that glow in the corresponding region of the spectrum, for example the Horsehead, Cocoon and California nebulae.
