High-ISO stitching can be problematic, and sometimes stitching them can be counter-intuitive.
The biggest giveaway for the stitch lines is banding, and the reason you get banding is because the stitchers automatically blend a somewhat wide region between adjacent images to mask the stitch line and balance any exposure differences.
With normal images this works great the majority of the time. What causes problems with high-ISO images is that this blending is effectively layering & averaging images, which is a very effective method for reducing random image noise. So you have a large image with normal high-ISO noise, but with bands which have less noise.
So the trick is to adjust the stitching settings so that the blend width is very very small, just a few pixels, or perhaps even zero so that the images are hard-cut. This also requires that the images be well-corrected for exposure, color, and vignetting... and very precisely aligned so that the edges match, as the blend region won't hide these problems.
Hope that helps. Your photo is fantastic by the way. _________________ Sigma DP1, Nikon D40 (hers ), Polaroid x530, Pentax P30t, Pentax P50, (P30t/P50 K-A to Nikon F body mount conversion)
