Instructions
Turn down the telescope's flip mirror, using the "flip mirror controls" near the photo port at the rear. Remove the cover from the photo port.
Combine the short and long pieces of the T-adapter -- screw the long adapter section into the rear of the short section.
Screw the T-adapter combination onto the photo port at the rear of the telescope -- use the short side of the adapter -- and then screw the T-mount onto the end of the T-adapter.
Remove the lens from your camera and replace it with a compatible T-mount. Screw the T-mount onto the T-adapter.
