At 13mm focal length on a 500mm system, it delivers \u003cstrong\u003e38× magnification\u003c\/strong\u003e with the sharpness and contrast that have made the Nagler series the absolute benchmark in astronomical eyepieces.\u003c\/p\u003e\n\n\u003ch3\u003eAl Nagler's \"spacewalk\" — 82° of total immersion\u003c\/h3\u003e\n\u003cp\u003eThe Nagler concept was born from Al Nagler's ambition to recreate the naked-eye visual experience — but with much greater magnification. The \u003cstrong\u003e82° AFOV\u003c\/strong\u003e creates a fully immersive observing experience: no sense of looking down a tube, but of floating in space. The \u003cstrong\u003eType 6\u003c\/strong\u003e is the most refined evolution of the Nagler design for short focal lengths: at 13mm it's the longest focal length in the series, ideal as a lower-power eyepiece for deep-sky observing while keeping the same \u003cstrong\u003e12mm eye relief\u003c\/strong\u003e and a compact profile comparable to the original 7mm Nagler — qualities that make it ideal also for spotting scopes via a 1.25\" adapter.\u003c\/p\u003e\n\n\u003ch3\u003eOptimised for fast telescopes\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e7-element, 4-group design\u003c\/strong\u003e uses special high-index glass types, including lanthanum and fluorite-type glass, with proprietary TeleVue coatings to correct astigmatism, coma and field curvature even at \u003cstrong\u003efast focal ratios\u003c\/strong\u003e. The \u003cstrong\u003eproprietary multi-layer anti-reflection coating\u003c\/strong\u003e ensures over 99% light transmission per surface with neutral colour and maximum contrast. \u003cstrong\u003eBlackened lens edges\u003c\/strong\u003e eliminate stray internal reflections.\u003c\/p\u003e\n\n\u003ch3\u003eConstruction and compatibility\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e1.25\" (31.75mm) barrel\u003c\/strong\u003e features \u003cstrong\u003efilter threads for standard astronomy filters\u003c\/strong\u003e, a safety undercut groove and a rubber grip.
