Thanks Paul.
I used to think that widefields don't suffer from seeing but in closer look you can see the difference in star resolution in the various panels shot under different conditions. The best night was the panel in the bottom center. The bottom right and top left were shot in high wind. The Lagoon and Swan/Eagle pair were shot in average seeing.
When you stitch together the
good panels with the
bad ones the myriad of faint resolved stars turn into mush so you have to do the best you can to match the seams. This is not quite visible at 50% which is ok. I'm trying to portrait the whole area with decent resolution which the 150mm gives me. 100mm doesn't and 200mm is too narrow FOV. There is also a tilt in the field which I need to shim the lens for. To get top-res you'd need an FSQ106 and consistently good seeing. One day...
