Astro-Tech Titan Type II ED 40mm 2" 68 degree wide field eyepiece, ATT240

The Astro-Tech Titan Type II ED 2" 40mm eyepiece may well be the ultimate low power wide field eyepiece. This substantial (4.75" long and 18 ounces in weight) ED eyepiece has a wide 68 degree field of view, with pinpoint star images from one side of the high contrast field to the other. It provides superb wide field views with any telescope type. With an 8" f/10 catadioptric it provides a wide 1.36 degree actual field of view at 50x, almost three times the diameter of the full Moon.

The 35mm Titan Type II EDıs six-lens wide field ED optical design makes it a superb eyepiece for comfortable extended-period viewing of large-scale deep space objects like nebulas and nebula remnants, open star clusters, and the star clouds in Sagittarius. It has the high contrast and bright images that make faint nebular wisps pop out against a very dark sky background, as well as showing you myriad subtle levels of contrast in bright emission nebulas. Pinpoint stars across the entire field make open clusters look like a handful of diamonds scattered across a black velvet cloth.

The stunning wide field views you will see in this 2" 40mm Astro-Tech Titan Type II ED eyepiece will take your deep space observing with a longer focal ratio scope to an entirely new and higher level, at a price/performance ratio no other top-quality eyepiece can touch.
