Thanks Marco - exactly what I did. Shame PNG - which really is for web anyway - won't seemingly save as well as the jpeg will. I guess just have to save at maximum jpeg always .
I like how PBase works, so was worth the $23 US.
The FSQ is a remarkable scope. I checked focus later in this run since it got cold FAST, and it showed out focus some on the Bahtinov. Even so, the image, despite the plumper star mass, looks OK really.
I refocused and did Antares region for 2 exposures (before I just did not want to tolerate the cold!), and the sharpness was absolutely pinpoint amazing (temp had stabilised both climatically and scope at 4°... that is COLD for here!!!).
I NEED Robofocus/Sharpsky - got to stop putting it off. Now what to sell?
