Astronomik H-Alpha 12 nm Nikon XL Full Frame CCD Clip Filter



  • This Astronomik H-Alpha CCD Filter employs the Nikon XL Full Frame clip format for compatibility with Nikon D800, D810, and D850 full frame DSLR cameras
  • Designed with the finest technical standards in mind to permit the desired optical performance for deep sky CCD imaging
  • Permits H-Alpha emissions to pass through while blocking almost the complete rest of the visual spectrum as well as IR
  • Approximate FWHM of 12 nm
  • Blocks all unwanted light pollution, making it ideal for imaging planetary nebulae as well as the remaining vestiges of supernovae
  • German-made for superior optical quality!




More About the Astronomik H-Alpha 12 nm CCD Filter



For astrophotography with CCD cameras, this Astronomik H-Alpha 12 nm T-Thread Filter is the optimal narrowband filter. It features a 12 nm full width at half maximum (FWHM) for enabling the use of very fast optics with standard CCD cameras. The extension of f/number applications ranges from 1:2.8 to 1:15. Transmission losses and chromatic aberrations can be a problem with other filters. With the H-Alpha 12 nm Nikon XL Clip Filter, however, this will only become an issue when excessively bright aperture ratios of 1:2 or more are in play. This filter has a transmission of up to 99%. Furthermore, you'll find locating a guide star with cameras that have an integrated autoguider much easier with the Astronomik H-Alpha 12 nm CCD Nikon Clip Filter.



The contrast between objects with H-Alpha emission lines and the skyglow background is enhanced by the Astronomik H-Alpha CCD Filter. In addition, this filter completely cuts off light from spurious sources such as the mercury and sodium-vapor lines from street lamps, making it an outstanding light pollution filter! Due to the Astronomik CCD H-Alpha substrate's high optical quality, you'll see the same razor sharp stars you'd see if you were using your regular telescope.



Arriving in a durable, high-quality plastic storage case, the Astronomik H-Alpha 12 nm CCD Filter is parfocal with all other Astronomik filters. It offers complete obstruction of all undesired wavelengths in the visible and IR spectral bands. This filter contains a very thin substrate and is diffraction limited for maintaining the optical performance of your telescope. It is also highly resistant to the effects of scratching, aging, and high humidity.



Astronomik Nikon XL Full Frame Clip Filter System Compatibility



  • The Nikon XL-Clip Filter have been successfully tested with the D800, D810 and the D850, although some customers are reporting error messages when used in a D850 with AF lenses. All manual lenses and T-adapters work fine!

  • Nikon full frame cameras that are not listed above have not been tested yet.

  • The Nikon XL Clip Filter will not work with cameras with APS-C sized sensors or with the new mirrorless models.




Transmission Specifications



  • Over 97% H-Alpha line transmission
  • Blocks almost the entire remainder of the visible spectrum
  • Rejects undesirable infrared wavelengths




Please note this filter must NEVER be used for solar observing or imaging. Doing so will cause permanent damage to your eyes.
