I could add in a platesolve and resync on the 4th mag star to ensure the scope knows where it is pointing, before I swing back to the image co-ordinates.

Does that make sense? I suppose as I am refocusing between each filter, or every 60-90mins when shooting luminance or Ha, I haven't felt the need to automatically resync. I'm also using an OAG, so shouldn't have a flexure issue either.

Gotchya. Makes sense, thanks David. Not going to Astrofest? I'm there this Thurs. If this flu hasn't killed me in the meantime... see below

G'day H. Sorry, been a bit quiet last week or 2. Got this flu that just won't go away, got doc appt tomorrow, could be swine flu! No jokes about my surname please

Haven't seen or attempted that astrometric stacking. Will look into it. So the solve adds coords to the FITS headers I assume? Neat.
