TS (Germany) came back with their advice on using Nextar DX mount for DSO photography: not suitable...
This mount is actually installed on the Nextar 4SE and 5SE and is fitted with a spur gear, no worm gear.
TS recommends a Vixen GP-E instead. Reported PE is around 13" and nicely periodic.
I will motorize it with Nanotec stepper motors and a custom home made drive controller Goto capable (Pic-Astro).
For the scope, I will take the Celestron C80ED over the Saxon/Orion for its compactness, despite the rack & pinion focuser.
Total cost for scope-mount-drive will be 1200 Euros (A$2000)
Thanks again for your input
