Images Comparisons: 

By popular request, here are a couple more comparisons of astrophotos shot with and without the PNB586 glass. 






How it works: 

 The window is  made of a special type of glass called didymium glass. PureNight mounts in front of your camera lens with a standard square filter holder (sold separately).

PureNight greatly reduces transmission of yellow and orange light in the 575nm to 600nm wavelengths, the same wavelength of light that is emitted by high pressure sodium vapor lamps. Sodium vapor lamps are most commonly used on street lights and industrial lighting fixtures and so they are one of the most prevalent sources of light pollution for astrophotography.


Our  filter will reduce the effect of light pollution in your astrophotography for truer colors straight out of the camera. Photos made through the PureNight will have improved contrast and reduced haze from light pollution.


Premium Optical Quality:

 It is  precision ground and polished and features an anti-reflective multi-coating to greatly reduce the effect of internal reflections and ghosting that plague most filters when used at night with bright light sources in the image.
