Arcturus Broadband Nebula Filter 1.25
The Arcturus Broadband Nebula Filter uses the very latest in optical filtering techniques to produce a fine light pollution filter. The filter element is a material that has its passband precisely controlled through excitation by a laser. The material is then laser-cut and placed into a filter holder, resulting in a filter that blocks light at wavelengths typically found in outdoor lighting systems. The Arcturus Broadband Nebula Filter makes a fine light pollution filter that passes a very high percentage of light originating from stellar sources.

Arcturus NBPF Narrowband Hydrogen-Alpha 12nm Filter 1.25"
  • Take high-contrast CCD images of emission nebulas in full moonlight or in extreme light pollution with this specialized  narrowband h-alpha astrophotography filters
  • Astrophotography filter provides 90% transmission at H-alpha line of 656.3nm and very narrow bandpass of 12nm
  • Reveals subtle nebular details which are usually washed out by contrast-killing broadband light
  • Also works great in conjunction with other filters for more advanced astrophotography techniques
  • Astrophotography filter with metal filter cell threads into standard 1.25" camera nosepiece or any  Multiple 1.25" Filter Wheel
