    Frank, you ask “what are those issues or problems?

    My first glance caused my eyebrows to raise due to the absence of any atmospheric extinction near the horizon. I assumed, therefore, that the image was a composite of at least two photographs, the sky one having been taken at a higher altitude than its transposed ‘apparent’ altitude.

    Though not a photographer, I would also expect that the necessary exposure to gain such stellar detail would be long enough for there to be some ship’s motion effects visible, especially so at the tips of the spars.
