Specifically, the depth/thickness of the V or actual dovetail. Thanks.

But now the question is: The Celestron CGEM DX saddle is 0.375 (3/8") deep - is it normal to have a gap betweent the bottom of the plate and the saddle?

I tried the orange dovetail from celestron, but it's like an inch too short. Apparently the new C9.25 OTA have been shortened and the orange dovetails only fits these new. It's not clearly stated in the specifications so if it's your case, beware. About the cgem saddle, i assume is the same as the dx. But i don't get the point of them having a variable width. The width can varry but not enough to accept a narrow vixen style dovetail. So i assume it's only a system to clamp the dovetail and not to adapt to different width. Whatever, it's extremely difficult to install the c925 with the losmandy dovetail. You have to apply enough force so that the entire mount is shaking. Impossible to install without light, but at least, once installed, the OTA is secured. With the other OTA from celestron, c8, c11, that i assume havn't change in lenght, you'd be better with a new orange dovetail, IMO.

The orange extruded Celestron dovetails fit the best in these saddles. That said there isn't a problem with the gap, the saddle holds any of these dovetails just fine. If you want a really nice precision setup replace the CGEM OEM saddle with an ADM or similar model and use a good D plate. Moving side plate or "tip in" saddles like the CGEM OEM, Casady, and the ADM make "loading" a scope very simple. With these saddles you don't need to slide the dovetail plate in from the end. Instead you open the saddle a bit wider and you lay the dovetail plate in place and tip it in (one edge seated and then laying it flat and closing the other side of the saddle against it). These saddles tend to have wide jaws (often the full length of the saddle so they grip and hold very well) but dovetail plates don't always sit flat against the bottom of the saddle (hence some have the gap). End loading saddles like the Losmandy tend to fit the plate differently (no gap) but don't have jaws as wide and are a bit more difficult to load with a heavy scope.

The CGEM DX is not flat - it instead is round on the underside and attached to the mount with three screws.
