Nebula Filter H-Alpha 1.25-inch 7nm
We are introducing this High-quality and functional Nebula Filter H-Alpha 1.25-inch 7nm. 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 filter by Explore Scientific blocks all other stains (about all artificial lights) and over the hydrogen emission lines 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. This H-alpha mist filter by Explore Scientific has been refined exclusively for astrophotography. When the sky is lightly brightened, many emission nebulae only come and show up to the light. This filter is used and is shown to a full extent on the astrophotos. The Explore Scientific H-alpha nebula filters make astrophotography near cities possible, and despite the existing light pollution, their use leads to surprisingly good image results. 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!
