T2 - M48 Converter Ring with Female M48-thread and Male T-thread - 8mm Length
Low Profile M48 female thread to T2 male thread TS Adapter
Special adapter from 365Astronomy.
Converts a M48 male thread to a T2 male thread
The M48 female to T2 male adapter is a classic "problem solver".
With this adpater you can convert a male M48 thread to a male T2 thread with very little additional mechanical length.
Female M48x0.75 thread (2" filter thread with about 5mm depth)
Male T2 thread (M42x0.75)
Effective optical length: 8mm (not counting the T2 male thread, which is about 2.8mm long)
Outside diameter: 2"
A special adapter combination: if you combine this adapter with our TSVF230 extension tube you get a prime focus adapter from 2" to T2 without a stopping flange and without a safety undercut. According to our experience safety undercuts often do not work well with focusers with a compression ring. The effective optical length of this adaptation is zero, so it is ideal for applications with a critically short back focus distance, e.g. a Newtonian or Dobsonian telescope with a 2" focuser!
