360 Milky Way panorama construction

Hi,

I'm trying to construct a 360 Milky Way panorama like the examples below:
http://galaxy.phy.cmich.edu/~axel/mwpan2/mwpan2_Merc_2000x1200.jpg
http://galaxy.phy.cmich.edu/~axel/mwpan2/mwpan2_Aitoff_2000x1000.jpg

I'm using MosaicByCoordinates but can't get past about 120 degrees, after which the distortions blow up.

It doesn't seem what projection I choose. I've also changed the projection point from the center of the image to the center of the galaxy but no change in the result.

I have attached my rough results at 120, 150 and 180 degrees using the Hammer-Aitoff projection centered on the image.

MergeMosaic_150.jpg
MergeMosaic_180.jpg

Any suggestions would be most appreciated.

Raymond.
 
I have no idea if this will help or not but have you tried using the ImageSolver script on each of the tiles before running MosaicByCoordinates? ImageSolver (under the Image Analysis group in the scripts menu) has an option to do distortion correction and under its Advanced Parameters section you can select the projection. It updates the header of each tile with the distortion model and MosaicByCoordinates then uses that data.

Thanks for the suggestion. All the panels have been image-solved with advanced distortion applied (essential for stacking or averaging the panels together at some later point).
