The majority of the Meade LX-series accessories (including the T-Adapter, Off-Axis Guider and Tele-Extenders) may also be attached to the ED & APO series telescopes by using the Meade #07362 Universal Thread Adapter.
The Universal Thread Adapter screws into the 2.7" threaded inner diameter of the telescope's focuser and accepts the threads of LX-series accessories.
