I think, it was sitting definitely too long untouched on my hard drive. Finally, a few days ago I decided to work on this image and I'm glad I did it :)
Firstly, I took 5 vertical photos at 20mm; 1/3sec; f/14; ISO 100 with my Canon 50d and Sigma 10-20mm f4-5.6 and Hitech filters (2 stop HE and 3 stop SE). Then, corrected individual images in Lightroom and exported as tiff files for work in Photoshop, where I stitched those photos manually (auto feature didn't work for me at all) to achieve this 2:1 panorama. Later, I did a few minor adjustments such as contrast and color balance in Photoshop.
The high resolution of 9378 x 4689 pixel for large prints is available.
