First,I am not finding the Deep Space Tour in the Celestia Motherlode.So,I suppose a better one is being made.It will be nice if the Deep Space Tour at least supports 2k DDS textures.
Anyway,I don?t know how to include a DSO in the cel script.I put many addons like M31,M42,M1,M27 and so on in Celestia>Extras>Deep Space Objects,but even some of these,the script didn?t find they.
I specially don?t know how to include NGC2237(Rosette Nebula) in the script.
Which catalogues I need to have to make them work?
