In astrophotography, most cameras are connected to a telescope via a T2 thread (M42x0.75), which is the most popular international standard. However, in many cases, T2 and T2-ring adapters for connecting telescope focusers to a camera are not the correct focus distance. This is especially important when using correctors, reducers or flatteners in the image train. This extension tube set, which consists of 5mm, 7.5mm, 10mm, 15mm and 30mm tubes, will allow you to obtain almost any distance using various combinations. 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.
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.
Details:
- 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
- 5 x T2 extension tubes (5/7.5/10/15/30 mm)
- 1 x SC to T2 thread adapter
