I bought a used nexstar 11 GPS that came with a Baader 2" clickstop visual back. Unfortunately, the original 3.25 to SCT step down adapter that comes with this scope wasn't supplied. So now when I want to put it into my JMI hardcase to travel, the Baader clicklock makes it too long and it won't fit into the case. The Baader is one piece so I have to remove it completely which leaves the unthreaded 3.25 opening one back of the OTA bare. I need something low profile to cap the back end of the tube so it will be short enough to fit into the case. Any suggestions?

I cant seem to find a simple 3.25" cap, and the Celestron website doesn't seem to stock the 3.25 to SCT adapter.

Mike,
I couldn't find it on their website. I did find this:

http://www.scopestuff.com/ss_tscp.htm

But that's the cap that screws onto the adapter, not the adapter itself. Not sure if that's what you were referring to. Can you point me to the item you are referring to please.
Thanks

Ah you are correct, I misread your original post and thought you were looking for the threaded cap I referenced. am not familiar with anything tailor made for your need, except the old plastic sandwich bag and rubber band solution.

the old plastic sandwich bag and rubber band solution.

What about a 3.25" to standard SCT adapter plus a screw on SCT threaded or push in cap?

I had to resort to the old bag and band trick. :(

I actually have the SCT threaded cap for the smaller opening. I can't seem to find the reducer/adapter ring. I put a wanted notice up in the classifieds. We'll see what happens.

Talk to Celestron. I tried to get this part and they don't sell it, so the support guys just had them mail me one. FREE. And talk about awesome support.

Just get them to confirm the clear aperture on their adapter. The one they ship with some C11 otas is only 1.5 ".

The Baader or AP 3.25-2" adapter is a better solution, IMO
