[Standard Size] Standard 1.25" (31.7 mm) fitting diameter. Can be used with any astronomical telescope equipped with a 1.25" focusing device.
【62° Wide Angle】Focal length: 4 mm. Offering high magnification, it allows for a more detailed view of the lunar surface and other planets, making it ideal for observing the moon and planets. The eyepiece features a 62-degree apparent field of view and long eye relief, providing a comfortable viewing experience and a bright, high-contrast view.
【Superior Optical Quality】By incorporating a multilayer FMC coating on the high refractive index rhythmic transmission surface, chromatic aberration is minimized, resulting in a bright and natural field of view.
【Applications】The aspherical design corrects images and solves viewing distortion problems. Primarily designed for planetary observation, it's perfect for distant celestial objects. Ideal for observing the moon, as well as medium-sized star clusters, wide-ranging cloudy nebulae, and deep sky.
[Specialized Optical Manufacturer] SVBONY is committed to providing you with cost-effective optical products. Our products are sold in many countries around the world. We strive every day to be a company that our customers can trust.
The SVBONY 1.25" fully coated eyepiece is suitable for wide-field lunar observations, medium-sized star clusters, and wide-ranging cloudy nebulae. If you're new to stargazing and don't know what you need to meet your needs, here's something to help you make an educational decision: Considerations: Make sure you know which telescope and how to calculate the best magnification for the subject you want to see.
Magnification formula: Magnification = Objective focal length / Eyepiece focal length
Generally, if you don't exceed 50x magnification per inch of the telescope's diameter, the image will become blurry (for example, using an 8" lens would result in 8 x 50 = 400x magnification).
So, investigate what the best zoom level is for the object you want to see.
Apparent 62-degree field of view
Ultra-wide angle lens delivers maximum detail and sharpness across the entire field of view, capturing virtually distortion-free images.
Fully coated optical lenses
The FMC glass optics enhance light transmission, highlighting details of Jupiter; Saturn; Mars; Venus, and producing high-color achromatic images. The optical system features an aspherical eyepiece, ideal for non-celestial objects, primarily designed for planetary observation.
Standard 1.25" fitting diameter
Suitable for astronomical telescopes with standard 1.25" focusers. Ideal for wide-area lunar observations.
4mm focal length
Suitable for observing the moon; to see the lunar surface and other planets in more detail; ideal for viewing the moon and planets. Applause: Viewing landscapes; bright astronomical observations; nebulae; wide-field lunar observations; medium-sized star clusters; cloudy nebulae and deep-sky targets; viewing the moon and planets, etc. Please note.
Don't look directly at the sun; otherwise, it will burn your eyes.
