The included parts will allow you to couple your SLR or DSLR camera to the ETX rear photo port (or the top eyepiece port) for "prime focus" astrophotography or nature use. Much more versatile than the Meade #64 Adapter. The money saving combo includes our 1.25" prime focus adapter (#T125) , the appropriate T-Ring for your brand of camera, an ETX 1.25" Rear Port Adapter (#ETXVB) and a Parfocalizing Ring (#PRING).
The parfocalizing ring lets you make an eyepiece in your top port "Parfocal" with your camera. This will allow you to center and focus using an eyepiece in the top port (which is much easier than focusing in the camera viewfinder) and then just flip the mirror down and take a perfectly focused image. Parts are "T" threaded for compatibility with many other adapters. Constructed of aluminum with an anodized black finish.
