Dave from Kailua-Kona pointed me to some photography panorama software after I got a little fed up with Hugin. His advise was PTgui which isn't free (actually, it's quite expensive) but apparently is Very Good. I used to think that of Hugin so wasn't particularly optimistic.
So, here are two panoramas from just outside UKIRT taken a couple of weeks ago. I took four photos at four different positions. At each position I used Photomatix to create a fused image with exactly the same settings. Those four final images were then used to create a panorama using Hugin and PTgui.
It was just a quick go at capturing Mauna Loa and Mauna Kea's summit in one go while staying out of the 40-mph winds! Bear in mind that the PTgui version has watermarks all over it as it was the free trial version. Click on the images for the larger versions - the comparison will be clearer!
The final image from Hugin:
The final image from PTgui (with watermarks):
There's no comparison. I've put in an order with PTgui!
