I love the panorama function in the Spark. The DJI Go app can merge the photos and create the panorama for you, however, the quality is not the greatest.

I've tried photoshop to do the merging. However, in "auto" mode it deforms the images slightly too much.

Compare for yourself:

Merge from DJI GO


Merge from PS


One can specially notice the curvature of the horizon.

Have you tried a different software o different settings for PS?

A nice complete (not alway so user friendly but latest version improved things to a pretty good level) free opensource tool : http://hugin.sourceforge.net/

Have not used, but heard good things about Microsoft ICE.

I use Panorama Studio 3 Pro.  Does a very nice job and is easy to use.  I believe it's about $80 US.

Adobe Lightroom. It can stitch in 3 different perspectives.
