Photos merge in PTGui terrifically

PTGui is all right, almost.
27 shots (in landscape format) merged without any input from me. (Reshaped with some overlap to fit the page better)
The picture is from the top of Bodie Mountain (10,150') near the ghost town of Bodie, CA. The town is low in the image at about 108 degrees. It was 10F and wind was gusting to 40 MPH when I shot these so I overshot by 2 and a half pictures and shot 29 pictures which was 2 images past 360 degrees. PTGui kept putting the images in a ring until I deleted 2 to get back down close to 360 degrees. Then PTGui straightened them right up. The actual panorama I cut and pasted to get over 360 degrees to leave room for annotation. The bearing grid and text was done in Picture Window Pro on an image reduced in size to 48 megapixels so that it could be uploaded to SMUGMUG. Its aspect ratio means that it can only be sold as a digital download on a panoramic-print-free SMUGMUG. (Wow! XL, XX2, and XX3 are great for low aspect ratio panoramas even if we can't sell prints through SMUGMUG!)
For a 12000x600 (700KB) linear version with readable sized annotation:

Of course, this panorama has no wires against the sky. There are some power lines at Bodie at 108 degrees, 3 miles and Lee Vining at 188 degrees, 20 miles, so they don't show well. There may be sky areas where heavy processing of 8 bit data to increase contrast of distant peaks has left artifacts.
The pictures were taken soon after sunrise. The haze at low elevations to the southeast is from sunlight hitting alkali dust blown in from dry lakes in Nevada to the northwest but peaks above 11,000' in Nevada up to 120 miles out are visible above the dust. The highest peaks in Yosemite are 20 miles to the west. The Palisade peaks on the northeast side of Kings Canyon show 80 miles to the south.
So, PTGui works pretty well if you don't overfeed it. Picture Window Pro also does OK except that that it can't do some operations (like sharpening) on files much over 550MBytes without careful preperation. I had to limit PTGui to 8 bits to stay within this limit. The edge trimmed version of the original stitch is 71,538x2,781 and 597MBytes. PWP does have some difficulty with image dimensions over 65536 so I resized to 65,535x2,594 at 486MBytes to speed operations since I was going to downsize for SMUGMUG anyway.
