  • Specification: Color: Black; Material: Aluminum Alloy; Diameter: 44 mm / 1.73 inch; Height: 5.5 mm / 0.22 inch; Male Thread: M42 x 0.75 mm; Female Thread: M42 x 0.75 mm; Package List: 1Pcs M42 Telescope Extension Tube. (Note: Manual measurement may have certain errors.)
  • Advantage: The main material of the extension tube is aluminum alloy, which is light, easy to carry, and has good corrosion resistance. The internal thread design helps to eliminate stray light and reflected light, thereby presenting clearer and more detailed images.
  • Instruction: To connect, screw the male thread of one extension ring into the female thread of another extension ring, ensuring it is tightened. You can combine multiple extension rings of different lengths to achieve the desired spacing. Connect your camera (or eyepiece) and telescope equipment separately, and use the telescope focusing device to fine-tune the focus.
  • Application: This telescope extension tube is auxiliary equipment specially designed for photography enthusiasts and professional observers. It can solve the problem of focusing caused by the camera or eyepiece not reaching the correct focal plane. Suitable for various types of cameras, telescopes, eyepiece, and other devices.
  • Note: Please pay attention to the dimensions before purchasing, and when installing, please ensure the threaded connections are tight and secure.
