After spending an hour or so, waiting for the sky to clear (it was supposed to be clear, on Friday, from 1800hrs) I was able to carefully polar align my G11 using my polar scope.
My thanks must go too. The helpful advice, from Chesterfield Astronomer, Paul Collins during PSP211
Paul very kindly told me, where I have been going wrong all these years with my polar alignment.
And in a nut shell, told me. "Stop buggering about, with pointing models, as these don't make any difference to my initial polar alignment".
The Soul nebula. is huge. And I can only get the central part, on the Atik16ic chip.
I am saving to buy a 314L+. And I hope to have this next year, if all goes well.
I think this is one subject, that will fit nicely on that larger chip with the 66mm William Optics, focal reduced x.5
Here is 1 hour & 22 minutes guided image. Taken through my, William Optics Zenith Star 66sd, and guided through my 8" with the QHY5 and PHD.
Focal reduced to 400mm at F2, to better suite my guide settings in PHD.
All exposures are in HA and taken using seven minute exposures.
This was taken on Friday tonight, before the cloud rolled in
