Stellarium DSO catalog
The NGC catalog used in Stellarium currently has many mistakes. We need make new catalog of DSO who provide more accurate data of the nebulas and more information about the type of the nebulae. This info could be used to use icons matching the type of nebula, and also to draw ellipses for galaxies. Also we can used this catalog as base for adds some external cataloges of DSO.
The code change should be located in modules/
Skills needed: C++, Basic astronomy knowledge
Difficulty: easy, an ideal task to get started coding on Stellarium!
A possibly useful source of public domain data for e.g. Messier objects is the HyperLeda site. Although the site's main focus is galaxy data, other deep sky objects are included as well. SQL and multiple named objects searching is supported so pulling a list of objects should be easy.
From their web page: "Access and data provided by HyperLeda can be freely used, and the software is distributed under the Open Source GNU Public License. Usage of services and/or data is warmly encouraged."
