i've downloaded nearly every galaxy and nebulae add-on file from http://www.celestiamotherlode.net/, and i've even used links such as
cel://Follow/Sol:Jupiter:Io/2003-06-27T ... 66119&lm=0
(from m16-v2.zip and m16-v3.zip extracted to the extras folder) to try and view the eagle nebula, but when the URL is loaded there's nothing there. i've had zero success trying to view any kind of nebula in Celestia. i've tried searching for nebulae with the "Select Object" menu option, but it doesn't seem to recognize any of the names. What else should i try?
Unable to view nebulae
nebulae
This is what my addons directory looks like re: Crab and Eagle nebulae
