Panoramic Wide Angle
The 57°-72°panoramic wide angle provides you with the ultimate observation comfort. The field of view of each focal point is calculated using optical design software, which is really effective. The customer's intuition may feel that the field of view will be larger.
Dual Interfaces
Equipped with 1.25" and 2" interfaces. It is suitable for multiple telescopes.
Support Astigmatic Corrector
Zoom eyepiece with astigmatic corrector provides you a better visual experience. The rubber eyecup on the eyepiece can be removed. It has M43 T-mount underneath, which can be connected via an M43-T adapter(not included).
Aspherical Lens
Double-sided aspherical glass lenses 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.
Fully Multi-Coated Coatings are a great help for increasing the glass's light transmission and transparency, combined with the 6 groups and 9 elements construction to provide a clearer image.
Edge Extinction
This design can absorb unwanted light when observing objects, reduce the effects of light pollution.
Continuous focal length zoom of 8mm to 20 mm for a wide range of magnification without the need to switch eyepieces.
Long eye relief of 17 mm for comfortable viewing position, even for eyeglass wearers.
Rubber Eye-cup
The adjustable rubber eye-cup is comfortable for viewing with or without spectacles.
