TS Optics 3mm 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.
