SVBONY 1.25″ 2× Barlow Lens with M42 Thread (F9108A)

The SVBONY 2× Barlow Lens is a compact 1.25″ telescope accessory designed to double the effective focal length of compatible eyepieces. Built with all-metal construction and multi-layer coated optical glass, it is well suited for lunar, planetary, and general high-magnification observing.
2× Magnification Boost
This Barlow lens increases magnification by a factor of two, allowing observers to achieve higher power without using extremely short focal-length eyepieces. This helps maintain more comfortable eye relief while expanding magnification options.
High-Definition Multi-Layer Coatings
The optical elements are manufactured from pure optical glass and feature a multi-layer HD broadband green coating. This coating improves light transmission and reduces internal reflections, helping preserve image contrast and clarity.
All-Metal Construction
A durable metal housing provides strength and stability for regular outdoor use. The robust build helps maintain precise alignment between the telescope and eyepiece during observation sessions.
M42 Thread & 1.25″ Compatibility
The F9108A features a standard 1.25″ barrel for compatibility with most telescopes and eyepieces, along with an M42 × 0.75 thread interface. This makes it suitable for a wide range of visual observing setups and compatible accessories.
Compact & Portable
With a length of just 7.5 cm, this Barlow lens is easy to transport and store, making it a practical addition to both home and travel telescope kits.
