Nice try but that is ... so last century.
The point I was trying to make is that while telescope optics - and especially Questar - are a mature product, the available software and display technologies (hardware) are not - they continue to evolve very fast to the point they are obsolete after 2-3 years.
The enduring protocol that has survived is tcp/ip, over wireless links.
Conclusions: a 21st century mount must have encoders, and this not negotiable.
It must be capable of interfacing to external devices that can be replaced by the user - both for the user interface, and for catalogues of objects particularly those likely to change.
The notion of handsets with buttons, clunky text-based interfaces like 1970s game consoles and object databases stuck in handsets are all relics of the 20th century thinking conceived by old fellas now in their 50's. High time to "think different" as Steve would have said 15 years ago.
Lastly it is possible to run off rechargeables and route the cables inside a mount. Time to ditch the umbilicals tethering it to handset, car battery or a mains outlet.
The earlier remark previously about mating a Q to whatever mount is one solution. There are even commercial mounts that do all the above and can take a Q5 so it can be done, albeit with low-res encoders. But plug ugly and not something wife would approve of in the lounge.
I'd happily pay Questar for something that solves all of the above in a self-contained scope in a box that is also a work of art like the Q3.5, to the extent I'd be happy to have it in the lounge.
And now that I know there is a point in having encoders that have resolutions in seconds of arc, I'd also suggest a double fork essential - the mechanical errors arising from flexure in a 1 arm fork will be evident.
Price is not the issue - the functionality is the real decider.
