But sadly, as soon as a notification list opens. Every ap fan boy has to get on it. Production fills, and those who could really use it are waiting years. Make no mistake, I'm a fan boy. By the time the mount arrives,, my 80 year old eyes won't be able to see M13 through a telescope. (I was on the mak 10 list 20 years) :-)

What can AP do that others cannot?
1. reliability/customer service
2. sophisticated pointing model
3. sophisticated polar alignment
4. user/focused (understands needs of users).
So in terms of picking 3 out of the 5.
1) Tracking performance should be good enough to make having an advanced pointing model worthwhile. If the tracking performance is bad enough that a mount set at sidereal will give you the same result, it’s not taking advantage of the performance.
It is not clear to me how much guiding solves this. My understanding is that a good model avoids the need for guiding.
It is not clear to me how much clutches affect this target of performance.
it is not clear to me if corrections in DEC are needed after an AP model is created or if it’s just RA modifications.
I don’t know what pixel size to assume but I think 3-4 microns is a reasonable assumption.
2) You have hit it spot on that there are older hobbyists who would do better with lightweight mounts and there are plenty of young hobbyists who like to travel.
3) Make it as affordable as possible. The Stowaway lets a lot more people enjoy your optics.
Let’s call this the “AP Traveler GTO”.
4) if it is spec’d to meet the criteria of “good enough to benefit from a pointing model” versus just tracking with the 92/6.65 versus the 130GTX, how does that change the price and size?
Maybe for the 92/6.65 “good enough to benefit from a pointing model” it would still be “very good” with the overloaded 130GTX or C11.
