NEEWER 4 Pcs LS-T6 Extension Tube Kit Telescope Accessory for Astrophotography

• A "must have" accessory- Designed to be placed in front of the focal plane of your telescope to add length to the original tube, offering extra focuser back travel and the correct image scale for astrophotography?
• Combine extension tubes- The set includes extension tubes of 4 lengths: 5mm, 10mm, 15mm, and 20mm. Achieve different spacing as required by combining one, two, three or four tubes together - connect male threads with female threads?
• Standard T2 Thread- With T2 thread (M42x0.75mm) on both interior and exterior sides, the tubes can be easily mounted on a T ring adapter to connect to your camera and make focusing in astrophotography much easier. Note: they cannot be directly connected to a 1.25" eyepiece, but can be connected to a camera through an adapter ring
• Anodized Metal Build- Made of anodized aluminum alloy to stop any reflection, the sturdy extension tubes are built to last and withstand daily wear and tear
• Lightweight- Weighs only 1.94oz/55g. The tubes won’t bring extra weight to your telescope when filming. The lightweight design makes them easy to carry as well
