Ok, I have it figured out now. The object that's on this scope is a ASTRO-PHYSICS 2" VISUAL BACK. The Highpoint part is the reducer I needed.
So, why are things in astronomy so hard to figure out? The Highpoint site list it as a diagonal adapter and gives no information of thread size, nor do they say anything about SCT threads. Everybody says it is what I need, but don't explain why. So, do all of you just buy what they say to buy or do you whant the information on what you are getting.
If you don't understand then read through the thread as if you are new to astronomy and see if you can answer the simple question this thread started with. Note the word Newbie, then a simple question of an adapter that's call 3.25 x 2 SCT adapter. I even let everyone know it's for a Celestron C-11 A XLT.
I'm wanting to do outreach. I'm very mindful that most people don't understand astronomy and that's why they are there listening. I don't use acronyms (they are hard to keep up with). If I'm explaining a part, I have to give three definitions to it (2" visual back,,,, Celestron 2" eyepiece adapter SCT,,,, 3.29" male 16 threads per inch x 2" female x 24 threads per inch Celestron adapter).
Yes, this means I have listened to each and every one of the responses and I figured out what they meant, but it wasn't easy. I do want to thank all of you for helping and would like to ask all of you to remember how overwhelming astronomy is in the beginning stages. I thought I was asking for a simple adapter and it came back as I needed to spend $110.00 on a part that's not refundable, and without Thread and configuration info. Imagine my dilemma.
I do have the correct adapter now, Thanks. I'm sorry if I started any problems, and I am trying to correct myself. I just couldn't understand what was happening and I didn't have enough information to ask the question correctly.
