Not happy with this at all. Came with the inner ring loose. That was easily fixed with a small screwdriver. No it clicks into place firmly but there is a small bit of play when you touch the camera. You can twist the camera a small bit to the left/right. Checked online and this seems to be a common enough problem. Seems to be a matter of luck whether you get one that is fit for purpose

These appear to be solidly built and of a high quality and attach to the camera body firmly and with no play. Very good product.

If you have a DSLR and want to take photos of the stars, deep space objects and solar system objects with it, you need one of these.

These adapters connect to the camera body and provide a nice common T-thread to which you can screw in something else (for instance a T-thread to 2" adaptor) which then pops into your focuser in place of an eyepiece.
