Stars will be less dimmed. This filter has been optimized to block as much spurious light as possible and simultaneously provide the best performance for 'useful' light. A good filter for DSLR-, CCD- and film b\/w-photography as well as observation of deep-sky-objects with telescopes or photo lenses of all aperture f\/2 and above.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGood for 30 second exposures \u003c\/strong\u003ewith JPEG data directly out of the camera without any further processing.\u003cstrong\u003e \u003c\/strong\u003e(Standard setting use: Canon EOS M3 MC-modified, ISO 1600, at 12\/2.0)\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eMain use\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis filter will completely block emission lines of artificial light sources like streetlights (e.g. sodium- and mercury-vapor), as well as airglow.
