panoramic photo and question

Below is a panoramic photo that I've taken twice now (the first time I forgot to lock the exposure). This time I made sure all the settings were locked and I used Photoshop CS Automate>PhotoMerge and the panorama is put together perfectly, but I still get these diagonal seems in some of the places where the photo overlaps (most notable on the right side of the pic). What can I do to get rid of these? Am I doing something wrong in camera (all settings are locked) or is it a software issue?

unfortunately software automation for photo-merging isn't perfect. It is good for quick results but if you want a quality job you need to do it yourself.
 
I read that in the newer versions of Photoshop the PhotoMerge automation is much better. Any suggestions on other cheaper softwares that are better than the older photoshops at stiching panoramas? Maybe I need to pony up and upgrade my photoshop.
 
The Photomerge isn't perfect, even in CS3 and even with Advanced blending on. Usually, the problem is not the camera settings being locked, it is subtle shifts in atmospheric conditions and angle of light to the camera. Just as when you use a polarizing filter to change the way light affects your camera's sensor, changing its angle in relation to the sun does the same thing.

There is a tutorial that I can't find at the moment that addresses this, and what you do is merge the photos but keep them on seperate layers, and then using the Channels menu, go through each channel one at a time and match its grayscale value (using Levels or Curves) to its neighbor. Repeat and you have identically colored, saturated, and luminance skies.

Also, you can try the Clone Stamp set to Color or Luminosity, or use Adjustment Layers with their layer masks to get the sections you need blended closer to the bordering pictures.
