Before you embark on your next astrophotography adventure, consider the high-quality H-Alpha H-Beta OIII (Ha-HB-OIII) Imaging Filter, specifically designed for the 8" RASA. This innovative filter is your key to capturing breathtaking, detailed images of the night sky, even from the confines of a light-polluted backyard. The advanced technology of this filter allows for high transmission of light from emission nebulae, effectively blocking light pollution. This results in images that burst with detail against a stark, contrasting black sky background. The filter strategically eliminates the impact of light pollution by blocking specific wavelengths, while allowing the beneficial wavelengths associated with emission nebulae to pass through to your camera. The Ha-HB-OIII Imaging Filter is perfect for imaging emission nebulae like the North America Nebula (NGC 7000), Lagoon Nebula (M8), Orion Nebula (M42), and the Carina Nebula (NGC 3372). It transmits key Ha-HB-OIII wavelengths that produce high contrast for emission nebulae, with a transmission spectrum of 85% or greater at key wavelengths (486nm, 496nm/501nm, 656nm) and less than 0.5% transmission elsewhere. This durable filter, made by Celestron, a reputable brand in the field of astronomy and optics, is a narrowband filter that blocks much of the visible spectrum, allowing only specific wavelengths through. It is custom-engineered to work at F/2, ensuring none of the beneficial light from the nebula is inadvertently blocked. The filter is housed in a machined aluminum black anodized cell with a knurled rim for easy installation. An anti-reflection coating has been added to suppress reflections on the glass. It fits directly into the internal filter mount in the RASA 8's front lens cell, maintaining the optical performance for the entire system. Each filter comes with a foam-lined plastic storage case and retaining ring for safe storage. A spectral transmission graph unique to your specific unit is also included, verifying its performance. With the Ha-HB-OIII Imaging Filter for the 8" RASA, your astrophotography will reach new heights of detail and contrast.

If you're an astrophotographer battling the challenges of light pollution, the 1.25" 7nm H-Alpha Nebula Filter by Explore Scientific is your solution. This advanced filter is specifically designed to enhance the visibility of deep-sky objects, even in areas with significant artificial lighting. Light pollution, caused by street lights and other human-made sources, can severely compromise the contrast and perception of celestial bodies. However, with the H-Alpha Nebula Filter, you can effectively filter out a substantial portion of this interfering light, making it easier to capture stunning astrophotographs. This filter capitalizes on the properties of emission nebulae, celestial objects that emit light in specific colors, or emission lines. These emission lines are associated with certain chemical elements, in this case, the red glow of hydrogen. The H-Alpha Nebula Filter blocks all other colors, allowing only the emission lines of hydrogen to pass through. This means that almost all artificial light is blocked, including the disruptive light from mercury and sodium vapor lamps. The result is a remarkable transformation in your astrophotography. Nebulae become visible in areas that previously appeared empty without a filter. Even under slightly brightened skies, many emission nebulae are brought to life with this filter, revealing their full extent in your astrophotographs. The 1.25" 7nm H-Alpha Nebula Filter is a game-changer for urban astrophotographers, enabling you to achieve surprisingly high-quality image results despite the presence of light pollution. Each Explore Scientific nebula filter comes with an individual test report, assuring you of its superior quality. This filter is an essential tool for every astrophotographer seeking to capture the beauty of the cosmos amidst the glow of city lights.

In addition to the turbulence in the air, the brightening of the night sky is the greatest obstacle to observing faint objects beyond the solar system. Street lights and other artificial lighting mean that the sky in human settlements is no longer properly black. As a result, the contrast and thus the perception of the deep-sky objects also suffer. Depending on the type of celestial object, however, part of the interfering light can be filtered out, thus making it easier to photograph the objects.The Explore Scientific H-Alpha filter uses the property of the so-called emission mist. These objects glow in certain colors, the so-called emission lines. The emission lines are linked to certain 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. In particular, the disruptive light from mercury and sodium vapor lamps is effectively blocked. The effect is amazing: Suddenly fog becomes visible in the photos in places that appear completely empty without a filter.The Explore Scientific H-alpha mist filter has been developed exclusively for astrophotography. Especially when the sky is slightly brightened, many emission nebulae only come to light when this filter is used and are shown in 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 supplied with an individual test report - so you can be sure that you are receiving high-quality filters.

Where light pollution and atmospheric turbulence often hinder the observation of deep-sky objects, the Explore Scientific 2" 7nm H-Alpha Nebula Filter emerges as a game-changer. This advanced filter is specifically designed to combat the challenges posed by artificial lighting and the brightening of the night sky, which can drastically reduce the contrast and clarity of celestial objects.The Explore Scientific H-Alpha Nebula Filter leverages the unique properties of emission nebulae, celestial bodies that emit light in specific colors, known as emission lines. This filter is particularly attuned to the red glow of hydrogen, one of the most common elements in the universe. By blocking all other colors, it effectively filters out nearly all artificial light, allowing only the hydrogen emission lines to pass through.This precision filtering results in a remarkable effect: nebulae, often invisible in photos due to light pollution, suddenly become visible, revealing the hidden beauty of the cosmos. The filter is especially effective in blocking disruptive light from mercury and sodium vapor lamps, common sources of light pollution in urban areas.Designed exclusively for astrophotography, the Explore Scientific H-Alpha Nebula Filter enables photographers to capture stunning images of emission nebulae, even under brightened skies. The filter's use can lead to surprisingly high-quality image results, making astrophotography near cities a reality.Each Explore Scientific Nebula Filter comes with an individual test report, assuring you of its high quality. Whether you're an urban astrophotographer seeking to overcome light pollution or a professional aiming for the clearest images of deep-sky objects, the Explore Scientific 2" 7nm H-Alpha Nebula Filter is an essential tool in your kit.
