These hard-coated narrowband filters are designed and specified with bandwidths as narrow as 0.15 nm, the industries' highest transmission levels, and wide-range out-of-band blocking. Single-cavity and multi-cavity filters are available. These ultra-narrowband filters are ideal for LIDAR, astronomy, Raman spectroscopy, and a variety of laser 2.強力な光害カット効果、ナローバンド撮影のようなハイコントラストな星雲撮影に役立ちます。 3.輝線星雲、惑星状星雲、超新星残骸の撮影に適しています。帯域幅が狭いため、sv220が都市部などの光害の多い場所での天体撮影に最適なフィルターです。 Narrowband imaging is a powerful tool in an astrophotographers kit, let's talk about how allowing less light through can actually makes you images better.
