SvBony 5x Barlow Lens 1.25" (Pre-owned)

The SvBony 5x Barlow Lens is an optical accessory designed to increase the magnification of telescopes with a 1.25" focuser. Here's what you need to know about it:

1. Magnification: The Barlow lens magnifies the image by a factor of 5x when used with a telescope. This means it effectively increases the focal length of your telescope by five times, resulting in higher magnification of observed objects.

2. 1.25" Barrel: The lens has a 1.25" barrel diameter, which is a standard size for many telescopes' eyepiece holders (focuser). This size ensures compatibility with most telescopes that use 1.25" eyepieces.

3. Multi-Coated Optics: The lens likely features multi-coated optics to reduce reflections and increase light transmission, resulting in improved image contrast and brightness.

4. Versatility: The 5x magnification provided by the Barlow lens makes it useful for observing objects at high magnification, such as planets, lunar features, and double stars. It can also be used for astrophotography to capture detailed images of celestial objects.

5. Construction: The SvBony 5x Barlow Lens is typically made of metal and high-quality optical glass, ensuring durability and optical performance.

6. Compression Ring: Some Barlow lenses may feature a compression ring mechanism to securely hold eyepieces without damaging their barrels.

7. T-threads: Some Barlow lenses come with T-threads at the top for attaching DSLR cameras or other imaging devices directly, allowing for prime focus astrophotography.

8. Eyepiece Compatibility: The Barlow lens should be compatible with any standard 1.25" eyepiece, allowing you to use a variety of eyepieces with different focal lengths for various magnification options.

9. Usage: To use the Barlow lens, insert it into the telescope's focuser, then insert the eyepiece into the Barlow lens. This combination effectively increases the focal length of the telescope, resulting in higher magnification.
