I use THIS on top of my CGEM Tripod and it works great.
I did replace the upper hex bolts with hand screws to make it easier to remove the mount from the pier.
Your post confirms my intention of using an Atlas extension for use on a CGEM. I emailed an Orion rep and he said that the Atlas extension would not work with a CGEM.
Anyway, it seems that the Atlas extension works pretty well on a CGEM mount and tripod. I'm planning of getting one. Thanks.

2. Pictures on the vendor sites always show the tripod extension upside down for some strange reason, so don't let that confuse you.
3. You will unscrew the alignment peg from the CGEM mount and screw it on the top of the extension instead. Which means there is nothing to keep the bottom of the extension from turning on the mount except friction. Some people on this site have complained about that happening when they accidentally bumped into the OTA. I put a strip of duct tape around the inside hole on the top of my CGEM mount to make the fit much tighter and increase the friction to the point where mine does not turn, no matter what I do to it.
4. It is a good idea to replace the 3 silver hex screws with longer bolts which you should be able to obtain from ACE harware. This is a good idea because to separate the telescope mount from the extension you will be removing these bolts every time you setup and takedown the mount. They are small and easy to drop in the dark. I would not even own this extension without the replacement bolts. I will include some pictures of the bolts in my next posting.

I bought mine at a hardware store and they were a little to long so I cut them down to 36mm and then attached a 2mm washer followed by an 18mm long metal sleeve using some glue. The washer and sleeve are necessary because you need to push the knob out away from the mount so it does not hit the mount. That leaves 16mm's of threaded area still exposed to attach the mount.
I think the M6-30mm at Scopestuff will probably be to short. Try an ACE hardware if you have one nearby. I found my bolts and sleeves at Elliot's hardware, but I think they are just a local chain. You can forget about Lowes and Home Depot they don't carry stuff like this in Metric sizes.
If you have never cut a bolt like this, you just need a hacksaw and a file. You have to file all the rough spots away and make a new starting groove on the bolt. Otherwise your bolt could destroy the aluminum threads on the mount. Best to get a 6mm nut and get it working with that first before you try to attach it to the mount.
