H-Alpha 1.25" 7nm Filter for Astrophotography - Explore Scientific
Available within 7 days
The Explore Scientific 1.25" 7nm H-Alpha filter is specially designed for astrophotography, allowing you to capture emission nebulae under a sky polluted by artificial light. This filter blocks almost all other colors, allowing only the emission lines of red hydrogen to pass through. It effectively eliminates annoying light from mercury and sodium vapor lamps, revealing details invisible to the naked eye and enabling the photography of nebulae that appear completely empty without a filter. With a narrow bandwidth of 7nm, this filter significantly enhances the contrast and clarity of faint nebulae, even in challenging urban conditions. An essential tool for urban astrophotographers wishing to achieve impressive results despite light pollution.
