Hi there, I am using a celestron C11. But I really need some help with aligning it up through auto 3 star align. The counter weight bar pointing approximately due north with the index marks aligned and locked. I aligned the eyepiece with the finderscope on polaris. I set the exact time and date, longitude and latitude for Dublin where I live. I then selected auto three star alignment method. I selected betelgeuse as my first alignment star, and that star was in the south east but when i clicked enter on it the telescope slewed down towards the western horizon. What am I doing wrong??
