Editing Stellarium (software) (section)

=== Planetarium dome projection ===
The fisheye and spherical mirror distortion features allow Stellarium to be projected onto domes.  Spherical mirror distortion is used in projection systems that use a digital [[video projector]] and a first surface convex [[spherical mirror]] to project images onto a [[dome]]. Such systems are generally cheaper than traditional [[planetarium projector]]s and [[fish-eye lens]] projectors and for that reason are used in budget and home planetarium setups where projection quality is less important.{{citation needed|date=April 2018}}

Various companies which build and sell digital planetarium systems use Stellarium, such as ''e-Planetarium''.<ref>{{cite web|url=http://www.e-planetarium.com/stellarium.htm|title=Stellarium Planetarium Software|work=E-Planetarium website|access-date=February 15, 2009|url-status=dead|archive-url=https://web.archive.org/web/20081201071949/http://www.e-planetarium.com/stellarium.htm|archive-date=December 1, 2008}}</ref>{{primary source inline|date=July 2019}}

''Digitalis Education Solutions'', which helped develop Stellarium, created a fork called [[Nightshade (astronomy software)|Nightshade]] which was specifically tailored to planetarium use.<ref>{{cite web|url=http://www.digitaliseducation.com/products-nightshade.html|title=Nightshade Astronomy Simulation Software|work=Digitalis Education Solutions official website|access-date=January 11, 2010}}</ref><ref>{{cite web|url=http://www.nightshadesoftware.org|title=Nightshade Astronomy Simulator|work=Nightshade official website|access-date=January 11, 2010}}</ref>{{primary source inline|date=July 2019}}
