Oh thanks Mark! I didn't know it was the same form factor. :-) Ordered!
Please report back once you get that extension installed. I'm interested, but not enough to risk $90+ to find out.

The Orion pier extension extends the base of the CGEM/Atlas mount, it simply replicates the top of the original CGEM/Atlas tripod.
The CGEM-DX uses the heavier CGE-Pro tripod with an adapter. Because of this tripod adapter I think you have a few options with one of Dan's pier plates.
1) You could buy the pier plate with the Atlas/CGEM adapter, the Orion pier extension then should bolt right up to that adapter, and then the mount on top of the pier extension. You'd leave the original CGEM-DX Celestron tripod adapter on the original tripod.
2) You could buy the pier plate for a CGE-Pro. You'd put the Orion pier extension between the CGEM-DX mount and the Celestron tripod adapter (just simply as if you were still using the tripod) and then bolt all this down onto the CGE-Pro compatible Pier plate.
I'm not sure which one would be the cheapest or easiest in the long run. I'd probably lean towards option #1 since it would incorporate one less adapter in the whole setup.
Another thought ... I'm assuming (always a dangerous thing ... lol) that you are having a pier support of some sort built to mount that Omega II pier. If so then why bother with the Orion pier extension? I would just make the pier support itself 6-8" taller (or order the Omega II that much taller) and not bother with any extra extensions. You'd still have the option of ordering Dan's pier plate in either the CGEM/Atlas version or the CGE-Pro version. Since you have a mount with the 1/2" center bolt you'll be using the additional mounting plate from BYO (again assuming), if so you'll have all kinds of height adjustment available from the 4 long bolts that attach that mounting plate to the top of the Omega II pier.
OK, this got kinda complicated option wise ... sorry about that. I hope though that it at least helps you to figure out what your options are. Ideally you'd want to have the least number of adapters and connections between the pier and your mount.

On the brighter side, the interior of the observatory is nearly finished. Just need to install the track and motor, and finish up the electrical hookup to the house :-)

Haven't heard back from Scott yet. Wiring is almost finished. Was able to test the red lights tonight. Nifty! I used the same fixtures that Carol has, one set for red and another above it for white light. Both legs have dimmers. Looks awesome!
