Extenders (or extender tubes or extension tubes) are an important astronomical accessory for imaging when the camera sensor is to be placed at the correct back focus distance (often 55mm) of e.g. focal reducer or field flattener with/without filterwheel, OAG or filter slider in the image train.

ZWO offer three fixed length extenders with different threaded adaptations for spacing purposes:

16.5mm M42 (Male) - M48 (Female)

21.0mm M42 (Male) - M42 (Female)

22.5mm M42 (Male) - M48 (Female)

An example of an adaptor attached to a camera can be seen below:

An example image train with a spacer can be seen below:
