Nebula Filter H-Alpha 2-inch 12nm

We introduce this High quality and functional Nebula Filter H-Alpha 2-inch 12nm. The brightening of the sky at night is the greatest obstacle to observing faint objects beyond the solar system and the turbulence in the air. Other artificial lighting and street lights mean that the atmosphere in human settlements is no longer appropriately black. As an outcome, the contrast and thus the perception of the deep-sky objects also suffer. However, depending on the type of celestial object, part of the interfering light can be filtered out, making it easier to observe the things.

This H-Alpha filter by Explore Scientific uses the property of the so-called emission mist. Those objects glow in specific colors, the so-called emission lines. The emission lines are linked to particular chemical elements - in this case, the red glowing hydrogen. This filter blocks all other colors (and thus almost all artificial light) and only lets through the emission lines of the hydrogen. The disruptive light from mercury and sodium vapor lamps is effectively blocked. The effect is impressive: Suddenly, fog becomes visible in places without a filter, appearing empty. The H-alpha mist filter by Explore Scientific has been developed exclusively for astrophotography. Most especially when the sky is slightly brightened, many emission nebulae only come to light when this filter is used and are shown to the 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 mist filters by Explore Scientific are supplied with an individual test report - to be sure that you are receiving high-quality filters. Buy to see it for yourself! Add to cart now!
