●aluminum alloy material: all metal structure and anodized aluminum process, using this extension tube obtain the correct image scale or the precise spacing required by the reducer or field flattener.
●m48 extension tubes, durable and reliable: crafted from high quality aluminum alloy with an anodized finish, these extension tubes are built to last. they provide sturdy and stable connection between your camera and telescope, ensuring precise image scale and spacing.
●variable combination: the distance you need be achieved by combining multiple extension of different lengths, you use, 2, 3 or extension according to your needs.


Description

1. Focusing Problem Elimination: The extension tube has M48 female thread and M48 male thread, which is used to solve the spacing problem in astrophotography and eliminate a series of focusing problems.
2. Eliminate Redundant Light: The design of female thread can eliminate stray light and reflected light, making the image clearer and more perfect.
3. Variable Combination: The required spacing can be achieved by combining several extension rings of different lengths, you can use 1, 2, 3 or 8 extension rings as required.
4. Type: Astronomic telescope M48 threaded extension tube, the height of the extension tube is 3mm, 5mm, 7mm, 10mm, 12mm, 15mm, 20mm and 30mm.
5. Aluminum Alloy Material: All metal structure and anodized aluminum process, durable, using this extension tube can obtain the correct image scale or the precise spacing required by the reducer or field flattener.
