Nebula Filter H-Alpha 1.25-inch 12nm
We are introducing this High-quality and functional Nebula Filter H-Alpha 1.25-inch 12nm. Additional to the air turbulence, The greatest obstacle to observing faint objects beyond the solar system is the brightening of the night sky. The atmosphere in human settlements is no longer appropriately black because of the street lights and another artificial lighting. The contrast and so the perception of the deep-sky objects also suffer. Nonetheless, depending on the type of celestial object, part of the interfering light can be filtered out, making it easier to photograph the things.
The H-Alpha filter by Explore Scientific uses the property of the so-called emission mist. Those objects' "so-called emission lines" glow in specific colors, and the emission lines are linked to particular chemical elements, "the red glowing hydrogen."This nebula filter by Explore Scientific blocks all other colors (about all artificial lights) and over the emission lines of the hydrogen by oneself. The disruptive light from sodium vapor lamps and mercury, in particular, is effectively blocked. The effect is impressive: Suddenly, fog becomes visible in places that appear utterly empty without a filter. When the sky is slightly brightened, many planetary nebulae, emission nebulae, only come to light when this filter is used and are shown to a full extent on the astrophotos. The H-alpha nebula filters make astrophotography near cities possible, and their use leads to surprisingly good image results despite the existing light pollution. A must for every urban astrophotographer.
The Explore Scientific mist filters are equipped with an individual test report to ensure that you receive high-quality filters. Buy to see it for yourself and add it to your cart now!
