The Meade 9 mm Xtreme Wide Angle XWA 2" Eyepiece provides spectacular wide field/high to medium power images with telescopes having focal ratios as fast as f/4. It is superb with fast f/ratio reflectors, such as Dobsonians, giving you both an immense field and a good 2 mm exit pupil with the typical f/4.5 Dob that is very effective at darkening the sky background so that faint stars and diffuse objects pop out more clearly.
Its very wide field also makes it convenient for moderate power lunar and planetary observing with Dobsonians, as you have much longer to observe before the planet drifts out of the field and the scope has to be repositioned. That said, it is worth noting that the new 100-degree 9 mm Meade Extra Wide Angle is marvelous for open clusters, nebulas, galaxy clusters and globular clusters with any telescope capable of using a 2" eyepiece.
The 100-degree apparent field of this new 9 mm Meade Extra Wide Angle eyepiece is nearly 50% larger in area than an 82-degree field eyepiece.
