The Nagler Type 7 series was developed as a natural extension of our highly regarded, 85°, limited edition Apollo 11 eyepiece. However, the series can also be thought of as an extension of the long eye relief Nagler Type 4 concept. With the all-new Type 7 design layout, we achieved our goal of Apollo 11-like performance across a series of focal lengths that are eyeglass friendly.

The ADC corrects the dispersive effects of Earth´s atmosphere. You will get sharper images of planets and moon.

  • The Atmospheric Dispersion Corrector is a revolution in observing and imaging objects.
  • Through the use of 2 high quality prisms, it corrects the false colour introduced by the earth´s atmosphere.
  • When used for planetary imaging, it changes the clarity of the image dramatically, particularly in the luminence channel when LRGB imaging.
  • Adaption is simple through T2 thread on both sides
  • You can use the ADC for visual and photography
  • You see the result very clear through the eyepiece

This filter was developed to suppress light pollution for colour and monochrome cameras and offers more balanced RGB colours.

  • ltair TRI-RGB is great for broadband objects such as mixed emission / reflection nebulae, comets, dust clouds and galaxies, but it also allows the major emission nebulae lines through. It covers both broadband AND narrowband targets.
  • TRI-RGB complements the Altair TriBand and DualBand filters by adding star colours.
  • TRI-RGB and works with fast or slow focal ratio telescopes and camera lenses. 
  • TRI-RGB is not only for light pollution control. It works very well under dark skies too by enhancing colour purity, airglow and reducing channel crossover in colour CMOS and DSLR cameras.
  • Although primarily intended for colour cameras, TRI-RGB can be used for a cleaner luminance channel with a mono camera. 
  • High transmission peaks with steep sides enhance contrast, together with almost total suppression of unwanted light, at OD4/5 (0.01%~0.001%) over the majority of unwanted visual wavelengths.
