Optolong L Pro Light Pollution Filter. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings. It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background.
Optolong LPro Broadband Light Pollution Filter 2" Rother Valley from www.rothervalleyoptics.co.uk
By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings. The filter is designed to enhance contrast and we must say, it does amazingly well. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial light including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen.
You Can Easily See The Difference Between The 1St And 2Nd Images.
Add to wish list compare this product. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lights including mercury vapor lamps, both high and low pressure sodium vapor lights and the unwanted natural light. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula.
This Is A 2 3Nm Dual Band Mounted Filter Designed To Drastically Reduce The Effect Of Light Pollution.
Standard 2” mount optolong claims that the l‐pro (l‐professional) filter is designed to improve the visibility. It also blocks artificial light from mercury. Light pollution filter do not eliminate the effects of light pollution or increase the object’s brightness.
In This Comparison, It’s Easy To See The High Contrast That The Uhc Filter Gives, Which Is Why Is Good For Deep Sky (Emission Nebulae.
I had tested the standard 2” version that suits the nosepiece of my ccd camera. The filter is designed to enhance contrast and we must say, it does amazingly well. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial light including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen.
Producing Light Pollution, Deep Sky And Planetary Filters.
As low as $ 6.42 /month. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings. It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background.
It Blocks Light Pollution, Maximizes The Signal From Nebulae, And Darkens The Sky Background.
The balanced transmission allows astrophotos to be taken with minimal color cast to broadband emission objects such as galaxies, reflection nebulae and globular star clusters. All test results from this video are up on: Optolong filters are coming in standard 1.25” & 2” and 36mm & 77mm unmounted sizes;
