About This Product
Fully multi-coated ultra-wide eyepiece with 66° apparent field of view. The eye relief is 16mm, allowing you to experience a more wonderful "space walk". There are 4 different focal lengths for the 1.25 inch eyepiece. There is also a kit containing all four types. Focal length: 6mm, 9mm, 15mm, 20mm; You can freely observe objects of different distances and sizes.
With an ultra-wide angle of 66° apparent field of view, you can enjoy expansive views of the moon, star clusters, the Milky Way, and more. Multi-element design and multi-coating lens provide sharp images. Additionally, the image plane is flat and chromatic aberration is corrected, resulting in a clear image. The 1.25-inch eyepiece barrel is made of aluminum and has a black brushed interior to eliminate light scattering.
It is also threaded to allow attachment of a 1.25 inch filter.
■Importance of eyepieces
The eyepiece is one of the most important parts of a telescope. A single eyepiece can completely change the way a telescope looks. Even if you use it for different purposes, such as observation or gazing, it is important to have an eyepiece that can bring out the full potential of a telescope, and by owning one, you can continue to use it even if you buy a new telescope.
■Recommendation of wide-angle eyepiece
For eyepieces with approximately equal focal lengths, the eyepiece with a wider apparent field of view will have a wider actual field of view. An eyepiece with a wider apparent field of view allows you to experience a more wonderful "space walk."
■Relationship between eyepiece focal length and magnification
It is calculated by the formula: Magnification = focal length of objective lens (mirror) ÷ focal length of eyepiece. Also, since the focal length of a telescope's objective lens cannot be changed, all magnification adjustments are made by replacing the eyepiece.
As you can see from the above formula, the longer the focal length of the eyepiece, the lower the magnification, and the shorter the focal length of the eyepiece, the higher the magnification. The lower the magnification, the wider and brighter the visible area, and the higher the magnification, the narrower and darker the visible area.
During actual observation, stars are observed at the optimal magnification by changing eyepieces with different focal lengths depending on the object being viewed.
