A place to hang out and chat about astronomy

Months ago I purchased a diagonal for my Celestron CPC 1100 that would correct the image through the eyepiece. I purchased one in Amazon months ago. Finally after a number of months, I was able to get my telescope out this past weekend. Unfortunately, I discovered that this new diagonal doesn't connect to my CPC 1100. What adaptor would I need to get in order to enable this diagonal to be installed on my telescope?

BTW - what is the exact technical name for such a diagonal? I don't recall what it was but once I get that, I can tell you the brand. The issue is, the diagonal that I purchased doesn't have the threaded connector ring that threads into the receiver at the back of the telescope.

Any help would be greatly appreciated.
