Bresser 6-piece extension tube set T2 and SC

Bresser set of 5 T2 extension tubes, additionally with SC/T2 thread adapter

With T2 thread on both sides, for exact distances and a secure hold of the cameras in astrophotography

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 focuser can be used with a simple T2 thread adapter with 2" plug-in diameter (item no. TSFA2).

However, Maksutov-Cassegrain, Schmidt-Cassegrain, ACF or Ritchey-Chrétien 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 SC to T2 thread adapter.
