Is the C8 too heavy for a Vixen GP?

I am in the process of buying a C8 SCT OTA that I am planning to put on a motorized Vixen Great Polaris (older model) mount. However, I am concerned that the C8 might be a bit too heavy for the GP mount. Currently I am using the mount with a C6 OTA, and this combination works great, with very precise tracking. I calculated the total weight of the C8 OTA + finderscope + diagonal + eyepiece, and it adds up exactly 15 lbs, which the max. load capacity of my mount.

Does anybody here have experience with using the Vixen GP mount carrying an 8 inch SCT OTA (C8 or similar)? Any issues? Any problems with the mount's longevity?

Regards.

Celestron used to sell the SPC-8 back in the mid to late '80s which consisted of a C8 on a Super Polaris mount - a close cousin to the Great Polaris. You will find an example in http://www.telescopebluebook.com/

As you have calculated the C8 is at upper limit of the mount's weight capacity but it will serve you well for a visual setup.

The GP is well suited to the C8. Even the SP was at least sufficient.
