Apologies for the copyright symbol.
I just may get this printed out at the original size of 12,000x3,000 pixels which itself was a crop.
At 300 pixels to the inch it would print out at 40 inches by 10 inches.
This is a first attempt and was stitched together using Canon's own DPP stitch software.
If a better sky crops up i'll retake it and try it again.
This is 5 landscape orientated images stitched together.
