Product Description

TS Neutral Density Filter ND 06 – 25% Transmission, used to reduce glare, especially from the Moon

Neutral Density filters are used to reduce glare on bright objects, thus improving observing comfort and increasing contrast.

The TS ND 06 is a medium grey filter
We recommend this filter for telescopes up to about 130mm aperture and in cases where you desire a moderate reduction in image brightness.

Applications
Grey filters can be used for planet observing, solar observing (only in combination with a true solar filter!) and for nature observing. The function is similar to regular sunglasses – the image brightness is reduced, meaning less strain for your eyes. The filter can be used visually and photographically. A ND filter is also helpful for observing binary stars by reducing the glare of the brighter component.

Adaptation
The filters are simply screwed into the 1.25″ filter thread of the eyepiece or camera adaptation.

Transmission
The smaller the percentage of light transmission, the stronger the filter is. For example a 25% filter will allow 1/4 of the light to pass through, while the rest will be blocked. A 12.5% filter will transmit only 1/8 of the light.

Scope of Delivery:
— Grey (Neutral Density) Filter 1.25″
