 Mr. Paul Bourke was so nice to set up an own page describing in great detail how to setup stellariums spheric mirror distortion feature, please visit his page at:

 I hope you will be satisfied with the results. Please send pictures of your new planetarium!

 #A dome. The dome should have a spherical inside. I suppose you can have good results with any dome larger than 2m in diameter, perhaps even with smaller ones.
-#A spherical security mirror. I recomment a 1/4 mirror, thats a quarter of a sphere. Something like 0.4 or 0.5m in diameter should be ok, for small domes you may need smaller mirrors, decide for yourself.

-Install the spheric mirror inside the dome. Imagine a coordinate system that is centered in the dome center. The z-axis points upward to the zenith and the y-axis points to some point on the horizon. Look into the direction of the y-axis. Now the x-axis points to a point on the horizon which is near your right hand.

 use any units you like).
 Install the projector approximately at (0,1,-0.2). Notice the z-coordinate -0.2: the projector is lower than the spheric mirror center so that it shall not occult parts of the image. In my implementation I assume that all light comes from one point, which in reality is not true. The projector_position in config.ini refers to this fictional point. It will lie somewhere inside your projector, I do not know, where.

 Mr. Paul Bourke has explained to me that some users like the following setup: They configure their dual head graphic card to show the same image on both outputs. One of them is connected to the projector, the other to an ordinary monitor that is used by the operator only. The operator wants to read the texts left-to-right, and therefore there shall be no image flipping on the stellarium image. Of course the projector then must be capable of doing image flipping, and must be configured to do so. Therefore I have introduced two new config.ini options in the [spheric_mirror] section: flip_horz (default=true) and flip_vert (default=false). This feature is available in current svn, and will go into the 0.9.x release.
