ZWO 2" nosepiece with M54 male threads. M54x0.75 male thread on one side and a 2" barrel with M48x0.75 female thread on the other side. Can be used as a 2" nosepiece with ZWO and other larger cameras that have M54 threads. Allows use of 2" astronomy filters at the bottom of the nosepiece. Made of black anodized aluminum.
The M48 sensor tilt plate is independently developed by ZWO and specially made to match telescope with M48 thread. The thickness is 5mm. It has several screw holes on the surface so that you can easily connect it to the M68 OAG and APS-C & full frame camera like ASI2600/ASI6200/ASI2400.
A great starter telescope for electronically assisted astrophotography. Price is excellent for the ease of use and quality of pictures. APP is easy to use. Very quick and easy to setup, especially when weather is unpredictable here in Thailand. Beats setting up the large rig.
