Unfortunately he has not learnt that there is something call a Horizont.

Agree with Hans, a small step waiting ahead for the photographer, giant leap for panoramas.
If I may a joke, according with Wikipedia
"The horizon (or skyline) is the apparent line that separates earth from sky"
One might think it wont apply to Mars 
I'm sure the next panoramas will be better as he'll learn about the horizon.
Nevertheless appreciate the work done and willing to share with others. Congrats for that!
Thanks for sharing,
Dorin

First of all they have to be connected to each other. As you can see they are all totally wrong. The problem in this pano is not to stitch the images at the horizont as they are far away and the large parallax does not matter.
The Rover is another thing, They do not at all fit automatically. I have not had time to stitch them yet as I could see they had some large problem.
The Same pano from the Spirit in 2004 was much better.

If is proper stitched and the parallax had cared of by mastering in photoshop/belnding, you can simply add some fake sky above until the horizon line is on the middle of the equirectangular i.e. if the equirectangular is 5000x2500 the horizon line should be around 1250 height in equirectangular. Can be done in MS Paint.
In PTgui, one should take care that the gray horizon line, visible in the before movie, to be on, well, horizon.
I apologise as I was too harsh in the morning posting before the cofe.
We should love and appreciate the people who put their effort in teaching other.
Their work is priceless, no one intentionally post bad tutorials, they write what they know and are giving to other.
I'm sure them are ashamed once somebody find some faults.
cheers,
Dorin
p.s. seems that I posted with Hans in the same time.
