TS Optics 30mm extension with M48 - 2" filter thread and 2" diameter
This adaptation has proven itself in many areas of astronomy. The extension tube is simply screwed into the M48 filter thread from 2" eyepieces or 2" adapters and therefore will extend the barrel. Thus the fitting accuracy of an adapter can be improved.
This tube is also important for astrophotography when the correct distance between corrector and camera sensor is concerned. Here, often just a few millimetres are critical.
