Extension tube with reciprocal filter thread

This adapter proved very important within many fields of the astronomy. The extension tube becomes simple screwed into the filter thread of 1,25" Eyepieces or 1,25" Adapter and extends thus 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.

Technical data:

- Metallhülse

- black anodized - reciprocal 1,25" Filter thread (28,5mm)

- Overall length is 25mm

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" extending. An interesting combination is also with our 0,5x Reducer (see picture left). The Extension Tube strengthens the reduction effect. (Link to the Reducer under "recommended accessories")
