What's wrong with just pointing to within the native out of box few arc mins, composing your frame shot and off you go, don't need any more than EQ6 or Meade capabilities for that
The high quality native tracking of teh PME coupled with normal autopguiding is as perfect as you need too, all this extra capability all seems a bit of overkill 
Maybe I am missing something?

Initially pehaps but apart from the capacity of the PME I want PEC and errors under 1 arc sec. Accurate go-tos are also important at long focal length.
If I have any problem with Tpoint I will just drift align and see how she looks. Then add the bells and whistles as go along, PEC mainly.
I got the mount counterweights solved today (weights from a gym shop and some magnetic tape to reduce the hole size. It was close to being in balance with the 3 counterweights as it turned out.
I got the mount at the right angle and installed the driver got it working on my computer. I got the Planewave focuser and temperature control working as well. The usual difficulties in doing the above with new equipment but I am ready to image now. If tomorrow night is clear then I should be up and running. The Starlight Express Lodestar in installed but it needs a special autoguiding cable it did not come with grrrr.
So the ST402 may do that work whilst waiting for the cable.
All systems go now.
The PME is quite user friendly so far.
Greg.

However, wouldn't accurate pointing make mosaic composition easier? I'm a long way from that - just did my first combination of a long and short exposure image tonight though!

Alt Az is easier to do accurate go-toos. With my NJP mount I found polar alignment the key thing for accurate go-tos. If go-tos wee off it was mainl polar alignment was not accurate enough.
