SkyWatcher T2-Ring for 35mm Canon EOS Camera
Sky-Watcher M42 T-Ring is a accessory you need if you want to take photo through a telescope or spotting with your camera. By using together with a simple T-Adapter (purchase separately), you will turn your telescope or spotting scope into a large camera lens.
To use this Sky-Watcher T2-Ring, simply remove the lens from your camera and attach the T-ring just like mounting a normal lens. The telescope side of the t-ring has threads that will accept a variety of camera adapters.
