Extension Tube with 1.25" Filter Thread, 25mm long
Extension tube with reciprocal filter thread
This adapter proved to be very important within many fields of astronomy. It can be simply screwed into the filter thread of 1.25" eyepieces or 1.25" adapters and will extend it by 25mm. At the telescope side you can screw a filter or adapt even a further extension tube. So you can extend the connector socket, without wobble.
Full metal construction
Reciprocal 1.25" Filter thread (28.5mm)
Overall length is 25mm
Ranges of application are : Connector socket extension for cameras and eyepieces, if the focus lies a little outside and thus there is no place for a conventional 1.25" extension. An interesting combination is also with our 0.5x Reducer. This Extension Tube will strengthen the reduction effect.
