Nice mount. I had one years ago. Make sure that you carefully adjust the RA worm to remove the slop inherent to the G-11. A little work adjusting the RA worm up front will protect against a lot of imaging headache. G-11's can have terrible periodic error - not all, but some. PE doesn't matter for visual use, but it can kill you when imaging, even after correcting and autoguiding. Still, the G-11 can be a nice mount.

Here's a nice page about the G-11:
