I experimented with connecting a Canon T3i to an ETX-90EC. I purchase the necessary T-apdater for the ETX along with the T-mount for the Canon. The connections all went fine. I focused in the eyepiece and the flipped the mirror. I add to refocus for the camera. The first images were okay.
I looked up in the Canon manual how to get the Live View not to turn off too quickly. I then read the section on Live View and learned how to manually focus. It was much better once I learned how to zoom in on the Live View. The automatic focuser was great but still not sensitive enough. Later, I found out there are speed settings on the focuser so will have to try that.
Overall, the configuration worked fine and ready to test on astronomy objects.
