The EXPLORE SCIENTIFIC H-Alpha filter allows photography of red glowing emission nebulae; ideal for use near cities, in slightly light-polluted skies.
- High-quality EXPLORE SCIENTIFIC H-Alpha filter
- Only lets the emission lines of hydrogen pass
- Absorbs all other emission lines and almost all artificial light
- Ideal for use near the city, with slightly lightened skies
- Band pass width: 12 nm
- Better contrast and more details achievable for urban astrophotographers
- Blocks almost all light from mercury and sodium vapor lamps
- Many of the red glowing emission nebulae are only visible in full expansion on photos taken with this filter
- In spite of the existing light pollution amazingly good image results are possible

Product information "EXPLORE SCIENTIFIC 2" H-Alpha Nebula Filter 12nm"
Apart from air turbulence, the brightening of the night sky is the greatest
barrier to observing faint objects beyond the solar system. Due to
streetlamps and other artificial lighting, the sky in urban areas is no
longer properly black. As a result, the contrast and thus the
perception of deep-sky objects also suffer. However, depending on the
type of celestial object, it is possible to filter out some of the interfering light making it easier to photograph the objects.
The EXPLORE SCIENTIFIC H-Alpha filter uses the characteristic of the so-called emission nebulae. These objects glow in certain colors, the so-called emission lines. The emission lines are associated with certain chemical elements - in this case the red glowing hydrogen. This filter blocks all other colors (and therefore almost all artificial light) and lets only the emission lines of hydrogen through. Especially the interfering light of mercury and sodium vapor lamps is effectively blocked. The effect is amazing: suddenly, nebulae become visible on photos in locations which appear completely empty without the filter.
The EXPLORE SCIENTIFIC H-Alpha Nebula filter has been developed exclusively for astrophotography. Especially in slightly light-polluted skies many emission nebulae only become visible and are shown in full expanse on astrophotos when using this filter. The H-Alpha nebula filters make astrophotography near the city possible and the use leads to amazingly good image results despite the existing light pollution. A must for every urban astrophotographer.
The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure to get high quality filters.

Warning notes
- General safety instructions DANGER Risk of eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device – especially the lenses – to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
- Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
- Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
- Do not expose the device to high temperatures.
