So what are the Pros and Cons of the AstroTrac and iOptron tracker mounts?

Some interesting questions. The Astrotrack only guides in RA, hence can only be autoguided on that axis.. Any Dec drift and you can expect eggy stars.
I had a look at the Astrotack website...they indeed claim a 15Kg payload....which sorry, really is laughable. I found it struggled with flexure with just a short focus 80mm refractor (3 kg)
Most camera tackers are just that: camera trackers. They are pretty similar in performance....just don't try and place too much camera+ lens on them and you'll get great results.
If you want a portable tracker+integrated tripod, sure the Astrotrack is a good solution..... but if you want a dual axis portable EQ mount, "none of the above" is the answer.
