- Focusing Problem Elimination: The Telescope Extension Tube Kit is equipped with both M48 female and male threads, allowing it to solve spacing issues commonly encountered in astrophotography. It effectively eliminates a range of focusing problems that may arise during the imaging process.
- Redundant Light Elimination: The inclusion of a female thread in the design helps eliminate stray light and reflected light, resulting in clearer and more images. The reduction of unwanted light interference enhances the overall image quality.
- Variable Combination: With the ability to combine multiple extension rings of different lengths, users can achieve the desired spacing. Whether you require 1, 2, 3, or even 8 extension rings, this flexible system can accommodate various needs and optimize the imaging setup.
- Astronomic Telescope M48 Threaded Extension Tube: Specifically designed for use with astronomical telescopes, this extension tube features an M48 threaded interface. Focal Length Extending Ring comes in various heights, including 3mm, 5mm, 7mm, 10mm, 12mm, 15mm, 20mm, and 30mm, providing options for precisely adjusting the spacing.
- Aluminum Alloy Material: The extension tube boasts an all-metal structure with an anodized aluminum process. This construction ensures durability and long-lasting performance even in rigorous astronomical imaging conditions. The use of this Focus Extending Tube Kit guarantees the correct image scale or spacing required by reducers or field flatteners.
