It's been cloudy for a couple of days so I've spent some time trying to join up the 2 panels of this mosaic and this is as good as it's going to get.
A dark site would improve this a lot, joining gradient ridden panels and maintaining colour is a real pain.
The final Tiff for this was 106meg making this 200K job pretty rank, so I uploaded a 50%, 3.2meg Jpeg
here.
Tak FS-60 @ F6.2 + Atik11000 2 panel mosaic with approx 6.5hours per panel.
