Some of the IMERSA talks mentioned Kolor Eyes as a preview tool. Checking out the "spherical" view on Kolor Eyes, found that it is a bit different from what we get using the polar co-ords tool of Gimp.
Kolor Eyes screenshot below, zoomed in a bit to get more of sky, rotated to make it similar to the Gimp screenshot.

This difference is because what we're seeing in Kolor Eyes is a "Little Planet" view and not a Fisheye view. This page has a discussion on the different projections. Kolor Eyes hosting has an option for Fisheye view also.
