  • Take high-contrast CCD images of emission nebulas in full moonlight or in extreme light pollution with this specialized extra narrowband H-alpha astrophotography filters
  • Astrophotography filter provides 90-percent transmission at H-alpha line of 656.3 nm and very narrow bandpass of 7 nm
  • 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 threads into standard 1.25-inch camera nosepiece, Orion Nautilus 1.25-inch Filter Wheel or Orion Multiple 1.25-inch Filter Wheel

 

Product Details

  • This 1.25-inch H-alpha filter was designed exclusively for deep-sky imaging of emission nebulas with CCD cameras, this high-performance filter transmits 90 percent of light at the hydrogen-alpha line of 656.3 nm and has a very narrow full width at half-maximum (FWHM) bandpass of 7 nm. The Orion 7 nm H-alpha filter blocks out all other light, including artificial light pollution and moonlight. It also blocks infrared (IR) light. The result is a dramatic boost in contrast, revealing subtle nebular details that are usually washed out by contrast-killing broadband light. Stars come out tight and sharp.

    The Orion Hydrogen-alpha 7 nm Narrowband filter is also ideal for capturing luminance data for LRGB color imaging of Hydrogen-alpha emission nebulae with monochrome imagers, such as the Orion StarShoot Deep Space Monochrome Imager II. When the monochromatic H-alpha image is combined with the exposures taken through red, green, and blue filters, the resulting color image teems with fine details that are "missing in action" in a standard color shot. This Extra Narrowband imaging filter is the perfect accessory for the StarShoot Deep Space Monochrome Imager II, and the 1.25-inch diameter filter threads into the nosepiece of the camera or the Orion Multiple Filter Wheel.

    Now that you can imagine capturing brilliant, high-contrast images of nebulas in full moonlight or in the thick of downtown light pollution you can bring it on, because you can do just that with the Orion H-alpha Extra Narrowband imaging filter!
