In astrophotography, most cameras are connected to a telescope via a T2 thread (M42x0.75) , the most popular international standard. However, in many cases, T2 and T2-ring adapters for connecting telescope focusers to a camera are not sufficient, as specific distances must also be observed. This is especially important when using correctors, reducers or flatteners. This extension tube set, which consists of 5 mm, 7.5 mm, 10 mm, 15 mm and 30 mm tubes , will allow you to obtain almost any distance using the corresponding combination. Each tube has a T2 interior thread on one side and a T2 exterior thread on the other side.
Most telescopes either include a T2 thread adapter, or the eyepiece can be used with a simple T2 thread adapter with a 2 plug-in diameter (item no. 0510365).
However, Maksutov-Cassegrain, Schmidt-Cassegrain, ACF or RitcheyChrétien telescopes may use a so-called SC thread. To allow you to use this extension tube set with these telescopes, the set also includes an SD to T2 thread adapter.
FEATURES
- 5 T2 tubes with lengths from 5 mm to 30 mm
- Combination of tubes allows you to obtain distances of 5 mm to 67.5 mm
- For exact camera distances in astrophotography
