Hi Alex, Fabien,

I think there would still be a place for W Steinicke's updated NGC catalogue as an option even with an improved default DSO catalogue compiled from simbad/HyperLeda. For example, the latest NGC lists distance/redshift information and corrects various mistakes present in older versions of the NGC/IC catalogue.

Alex, what did you have in mind for code refactor? I'd prefer to merge my branch with trunk first if possible.

Further to Fabien's suggestion of a "top 10 popular DSOs", I had a couple of ideas:
1. a bookmark/favourite feature (this could communicate with a server to make a global favourites list),
2. seasonal lists. I have a lot of old astro mags which have monthly sky tours (mainly N hemisphere).

Thanks,
Thomas

Hi lex and Fab.
 
I deleted the ngc2000.dat (actually I just removed it from all locations). Stellarium did not "bat an eyelid" it did not notice still read the ngc's from Simbad.
 
By the way Alex I looked at your new configuretion table effort. Great work I am slowly getting it into the pdf file. a big job as I have to re-format the tables and then add the data line by line.
