Moon filters reduce glare and allow for more comfortable viewing of any bright object through a telescope eyepiece. Although the bright Moon does not cause any harm to our eyesight it is very uncomfortable and often dazzles ruining dark adapted vision for astronomy.
This premium neutral density (ND96) filter simply threads into any standard 1.25" telescope eyepiece and transmits 25% of the incoming light without changing the colour transmission resulting in more contrast and comfort. Observers of the planet Venus will also find this filter very useful reducing glare from the extremely bright reflective clouds that cover the Venusian surface.
Made from premium optical glass and housed in a precision aluminium cell with the maximum available clear aperture. Supplied in a handy plastic storage box, an affordable quality essential for all telescope owners.
