Please take a look to my Panorama, with attention to the sky.
It is made from this picture:
There is an error in the stitching because they are from different colors on the sides... can you please help me with ideas?
Probably the photos were taken at different exposures or using auto white balance rather than consistent manual settings.
You will have to do some cloning/blending or add clouds from another image.
Yes you are correct.
Since my aerial pano was taken using a RC multirotor, at the sky I have the blades. After I flew, with the same camera settings I took a zenit/sky picture.
What I am thinking is that: does not correspond the angle used for stitching. In practice it will not be easy to know what portion of the sky would need to be align with the new photo taken.
