Hi Lucas,
Thanks for participating in the discussion. I like the Mesu mount, as I'm a fan of the ASA mount as well. Both mount look like they would eliminate the NEED for autoguiding, but as you have discussed, autoguiding is still necessary because of other factors, no matter how accurate your mount.
On the cost of mount + AO vs high accuracy mount, the high accuracy mounts are still a bit behind on the price equation. Your mount lists for Euro 7495 (about A$11k + tax and shipping), the ASA at Euro 5750 (A$8300 + T&S).
A Losmandy G11 is A$5200, + $1000 for the Ovision worm, which gets you to similar numbers for corrected PE. Add to this the (most expensive) SBIG AO gear (AOL $2k, MOAG $1k, RGH $800) and it comes to A$10k. But the key here is that all of this is new prices G11s come up often as used gear, as your stuff is so new (and the ASA as well), you can't buy secondhand. If you factor in secondhand prices (G11 $4k, Ovision $1k, MOAG $1k, RGH $400, AOL $1k), then it comes to $7400, which is approaching half the price of your mount. That said, if anyone wants to buy all my gear (as listed) for $10k I'll try out one of the ASA mounts and tell you what they're like!
I also realise that your mount can do extraordinary weights, which the G11 cannot, but not many of us have 65kg scopes.
Cheers
Stuart
