[Versatile Expansion Tube Kit] The M48 -focal length extension tube kit includes 8 pieces of different heights (3mm, 5mm, 7mm, 10mm, 12mm, 15mm, 20mm, 30mm) to solve distance problems in astrophotography unloadThese tubes are designed with M48 female and male wires, ensuring compatibility with most astronomical telescopes and eliminating focus problems.
[Precise Image Scale] This expansion tube kit is essential for obtaining the correct image scale or the precise distance required by reducers or field shipping. Its precise engineering ensures that your telescope setup is optimized for accurate and detailed astrophotography, making it a must-have accessory for serious astronomers.
[Improved Image Quality] The female wire design of these extension tubes effectively eliminates stray light and reflected light, resulting in clearer and more images. This feature is essential for achieving high-quality astrophotography and ensuring that your telescope captures the best possible visuals.
[Durable all-metal construction] Made of high quality aluminum alloy and finished with an anodized process, these extension tubes are built to last. The robust structure for all metals ensures durability and reliability even in demanding astronomical photography conditions, delivering its long-term performance and value.
[Customizable Distance] Achieve the precise distance required for your telescope setup by combining different lengths of extension rings. Whether you need 1, 2, 3 or all 8 rings, this kit offers the flexibility to meet your specific astrophotography needs, making it a versatile tool for both amateur and professional astronomers.
