Altair Lightwave Long Eye Relief Planetary Eyepieces have a comfortable 20mm high eye relief allowing you to place your eye comfortably within 20mm of the rear lens. Ideal for glasses-wearers or naked-eye observing. Altair Lightwave Long Eye Relief Planetary Eyepieces are ideal for high power observation of the Moon and planets due to the short focal length and effective multi-coatings, which enhance contrast. Divide the focal length of the telescope by the focal length of the eyepiece to determine magnification, i.e. 500mm telescope focal length divided by 3mm = 167x magnification power. The computer optimized multi-element design uses 7x lens elements for enhanced correction of astigmatism, chromatic and spherical aberrations, as well as a flat, sharp 55 degree field of view. All optics are fully multicoated to improve contrast and the surfaces feature a very smooth polish to control reflection and scatter around bright objects. Large rubber eye-cups eliminate stray external light for an immersive experience day or night, and can be folded back for eyeglass wearers.
