Although to answer your questions properly, yes it can be done, usually with an Argo Navis and a CAT etc. still costs loads !!
2.Orion (USA) and Skywatcher, although again, just announced, and not alot of news yet.
3. ? Cars when crossing the road?
4. Loads. the only current price i have for the 12" is $3100, whereas the ordinary model without tracking can be had for $1150. I called Andrews, and they said they hadnt posted anything online yet, as they would do so when they had thier very best price. for an Argo Navis and CAT? well, the AN is very reasonably priced, and a great piece of kit .. the CAT will cost a little bit more

Thank you for that info. Sirius Optics , which is where I got the telescope from , have Dob Go-to's coming in June. I know Go-to's and tracking are different, just thought i'd share that. :-)
Question 3--what to look out for , LMAO at your answer. I was actually referring to the quality or specs so I dont buy a dodgy one.
