2018-05-19 Partial Cygnus

Another test shot for the Pana 25.
This one renders quite better, though big stars are still saturated.
(and constellation is quite unrecognizable)

Color calibration was quite difficult with Regim, because this operation is designed for small fields.
I had to solve and CC on a smaller sub-field of the image, and it still has too many stars to choose from.
