Astro-Tech Titan Type II ED 30mm 2" 68 degree wide field eyepiece, ATT230

The Astro-Tech Titan Type II ED 2" 30mm eyepiece has a wide 68 degree field of view, so large that the tack-sharp image more than fills your eye. While it provides superb wide field views with any telescope type, it is particularly well suited for low power viewing with a fast focal ratio Dobsonian reflector. Its 30mm focal length gives you a 6.67mm exit pupil with an f/4.5 reflector, just about the largest exit pupil that a normal fully-dilated eye can accept, for the brightest wide field views possible.

The 30mm Titan Type II EDıs six-lens wide field ED optical design is superb for viewing large-scale deep space objects like nebulas, open star clusters, and the star clouds in Sagittarius. Its high contrast and bright images make faint nebular wisps pop out against a very dark sky background, as well as showing myriad subtle levels of contrast in bright nebulas. Pinpoint stars across the entire field make open clusters look like a handful of diamonds scattered across a black velvet cloth.

This stunning views you will see in this 3-7/8" long 11 ounce 30mm Astro-Tech Titan Type II ED eyepiece will take your fast focal ratio wide field observing to an entirely new level, at a price/performance ratio no other top-quality eyepiece can touch.
