## Description

It is convenient to observe planet. *Wide angle eyepiece, expand the view of sight. *Wider coverage, compatible with more brands. *Output images without edge distortion." "Panoramic Wide Angle 57°-72°panoramic wide angle provides you with the ultimate observation comfort" "Aspherical Lens The aspherical lens is designed to eliminate edge distortion, it has resolved the persistent issue of subpar edge image quality associated with wide-angle eyepieces, thereby transcending the visual constraints experienced by users." "Parfocalization Parfocal across the entire zoom range.There is almost no need to refocus when changing magnification."

Review: I bought this eyepiece and tried it out on my 6-inch f10 telescope. I observed the moon and the planet Jupiter. The eye relief and the width of the field of view were pretty good. The images seemed to be sharp and clear from the center to the edge of the field of view. The craters on the moon were wonderful. In a few minutes of very good seeing conditions, with the eyepiece focal length set close to 9 mm., I could observe much intricate and subtle shadings in Jupiter's cloud belts. Jupiter's four bright moons were neatly portrayed with no visible unwanted flare. This eyepiece seems to be optically really good. It is not overly heavy at around one pound in weight. The zoom control was slightly stiff in the cold air but still very manageable. A good zoom eyepiece can be very useful in observing faint galaxies and comets. You can sometimes see a faint galaxy pop into visibility as you slowly zoom from low to high power. The 2.5 to 1 zoom ratio was a bit low but this was probably necessary in the design to allow the field of view to be wide and the image quality to be excellent. I would like to see manufacturers make a 6 to 1 zoom eyepiece, or a compact, lightweight turret with four eyepieces covering a 10 to 1 ratio. I am including some photos of the moon that I took last year with my six-inch telescope, just to show what you can see with such a telescope.
Review: High quality build, solid feel, easy click to change magnification.
