The special characteristics of the L-e - Nhance allows amateur astronomers to get great results when imaging, even in urban skies degraded by heavy light-pollution, with just one filter! The L-e - Nhance optimized dual-band filter significantly blocks light pollution while allowing up to 90% transmission of H-Alpha, H-Beta and Oxygen III emission lines. - As you can see from the specifications below and the transmission curve chart to your left, Optolong designed this dual-band pass filter to retain the prominent colors of nebulae in RGB while blocking out most wavelengths of light pollution. This multi-purpose imaging light pollution filter even allows for SHO Hubble palette simulation with a few tweaks with your image processing software. - Optolong L-e - Nhance Filter Specifications - Blocking Range: 300nm - 1000nm - Blocking Depth: \u0026gt;99% light pollution line - TPeak: T\u0026gt;90%Substrate: B270Thickness: 1.85mm - Surface Quality: 60\/40Transmitted Wavefront RMS: �� \/4Parallelism (arcsec): 30s","brand":"My Store","offers":[{"title":"Default Title","offer_id":44606592286785,"sku":"P353528761838342877","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/7109\/4849\/files\/59c57d6cbed8de36a1e9a5cf5c792e5a32e95948e7c14e4ca9f5e7eb73eb38cb.jpg?v=1789608857","url":"https:\/\/aghbh.shop\/products\/optolong-l-enhance-light-pollution-dual-bandpass-imaging-filter-2-00-lnh-200","provider":"My Store","version":"1.0","type":"link"}
