Resizing data is a good way of getting improved resolution too. For this field for example, you could resize the FSQ lum to give greater resolution to the 100mm FOV. That way you get a pleasing FOV and resolution where it counts. Plenty of options to experiment with.

Thanks Jase. It works out to about 10 arsec/px even with the QHY9s small 5.4 um pixels. The processing was a bit lazy to be honest - I wasn't expecting anyone to zoom in too much so the keyhole area is blown. I've attached a zoom jpg which is pretty representative of what the master looks like with more considerate stretching right up close. Ok for a 1970s lens? Hmm, actually the tracking isn't anything to write home about zoomed in that far.....
