AP 600E QMD and 9.25" OTA?

I am about to become new to the world of AP mounts, as I've just purchased a 600E QMD from a fellow Astromarter. Delivery in 1 to 2 weeks. It will be installed on an existing pier in my back yard with lots of concrete underneath.

Most of my imaging is with an SXV-H9 with an FS-78 @ F6 (FL of 470mm) and a 60mm scope for the autoguider. I know this should be a good match for the mount.

I would like to at times install a 9.25" SCT OTA for some longer focal length (1450mm @ F6.3 with FR) imaging of smaller deep space objects with a 60mm scope for autoguiding. Do you think the mount will be capable of excellent images at that focal length with this load (25#'s or so)? What about at 2300mm @ F10? Or am I asking too much?

Thanks for your thoughts.

Scopes you mentioned should not be a problem for the 600 QMD you have in mind. The mount will easily up to 40 lbs of equipment

I would say not excellent but good and YES you might be pushing it.

If this was true why would any of us spend the money we have on our mounts or manufacturers bother to put larger RA gears in mounts geared for photography. I am sure your will be able to capture some images but beefing up your mount will always make it easier to get the nicer ones and increases the chance for that excellent one.
