Omegon Variable Polarising Filter 1.25"

Omegon Variable Polarising Filter 1.25" – Product description

Variable 1.25-inch polarising filter with continuously adjustable transmission from approximately 1% to 40%.

Key product details

• Lunar observing with larger telescopes
• Bright planets and terrestrial observing
• Observers wanting variable rather than fixed attenuation
• 1.25-inch filter thread
• Variable transmission approx. 1-40%
• Neutral grey brightness reduction

Product overview

A variable polarising filter consists of two polarising elements that rotate against each other. Turning them adjusts image brightness to the target and the observer's preference.

Suitable applications

• Lunar observing with larger telescopes
• Bright planets and terrestrial observing
• Observers wanting variable rather than fixed attenuation

Included equipment

• 1.25-inch filter thread
• Variable transmission approx. 1-40%
• Neutral grey brightness reduction
• Adjusted by rotating the two filter elements
• Compatible with many 1.25-inch eyepieces

Variable brightness instead of one fixed level

A thin crescent Moon needs less attenuation than a nearly full Moon, so a variable filter adapts more flexibly to different conditions.

Safety information

Not suitable as the sole filter for solar observing. The Sun requires a purpose-designed, securely mounted front solar filter.

Practical note

For solar observing, a polarising filter must never be used by itself. It does not replace a suitable front solar filter.
