FYI, an AP mount (or ME2) equipped with encoders all but eliminates PE... with the option of install at a later date when funds are available. Then I'd spend good coin on the latest AO unit after that.
Getting directly into a DD mount, today, in the 100+KG capacity range just ain't possible for most us (Skywatcher, if you're listening - bring out that EQ9/10 with direct drive please, to keep em honest)...

Unless the Chinese work out how to make high-res ring encoders for less that a few thousand a pop, (yep, that's the OEM cost) I can't see it happening.
BTW what happens to DD mount when it loses power? I've been told they simply fall limp....
...but that sounds a bit risky/disastrous for 100Kg of telescope etc. so you'd hope there is some sort of fail-safe.
Anyone know for sure??
