SVBONY T2 T Ring Adapter, Metal 1.25 inch Telescope Accessory, Compatible for Canon EOS Cameras Photography Dedicated CA1 Sleeve Extended Cylinder for Telescope

The set works well. It also includes an extension tube that I do not use as my camera achieves focus without it. However the T ring and the adapter's M42 threads are not machined perfectly and are a bit rough when fitted to the DSLR. The T ring adapter does not screw in tight, and instead keeps rotating to infinity after a certain point. So far this has not caused any issues in maintaing camera position and focus, but its a loose fit.

works setting camera to manual mode and adjusting the settings takes pictures just fine with the power magnification much higher than the the 250 normal zoom lens can be father away from wild life and still get a nice pictures, locks solid to camera.

Everything you need in 1 package. I wasn't interested in using the longer adapter but it has come in very useful. Only one pin locks a barlow or eyepiece in the chamber but it doesn't seem to be an issue as per picture, can be easily solved with a small piece of paper to wedge in the other side if you don't think it looks aligned.

No he podido tomar fotos aún, pero encaja perfecto en la cámara, tanto los adaptadores como el tubo extensor, no veo que pueda fallar, llegó un día antes de la fecha marcada

Se acoplo perfectamente a cámara Canon T7, y a Celestron C90 de forma directa, si lo ocupas con oculares hay algunos que x su tamaño no caben, pero es mejor usarlo directo a foco primario
