I see no option (or config.ini line) to turn them on. I also use hnsky and CdC. Both display stars below the horizon. If I've missed any comments or posts about this development, I apologize.

To see the stars, turn off the atmosphere (default toggle keu is A).

I meant to post this query in the Astronomy Software and Computers forum. I should have added that I see no stars below the horizon with ground, fog and atmosphere turned off.

If nothing else, perhaps a re-install is in order.

It didn't fix the "problem." I've partially fixed the "problem." I lowered the extinction coefficient to zero. However, I can't save the extinction coefficient at zero. I don't see any line in the config.ini file for the extinction coefficient. I could try another download of 0.11.2, but I'm inclined to think that if the download I have is corrupted, I wouldn't have been able to install 0.11.2.

Problem fixed by editing my config.ini file: [astro] ... flag_extinction_below_horizon = false ... Maybe this flag command was there before. Maybe it wasn't.

I ask because in reality they do, in a manner not so different from interstellar extinction. In my own crude software with which I create illustrations for some of my magazine articles I've added the option to do this. The effect is pretty realistic looking.

Generally, I appreciate flexibility and choices for display in a planetarium program. BTW, thanks for the replies. However, I'm still wondering why I had to edit my config.ini file. Those who replied that the stars below the horizon were there with ground, fog and atmosphere turned off did not mention the flag command to disable extinction below the horizon. I'm puzzled. Do I have a slightly different version of 0.11.2? I downloaded on 2 May. Post Extras:       amicus sidera Carpal Tunnel Reged: 10/14/11 Loc: East of the Sun, West of the M... Re: Stellarium 0.11.2: Stars below horizon gone [Re: Man in a Tub]       #5228993 - 05/18/12 10:39 PM Edit   Reply   Quote Quick Reply   I'm not all that conversant with the ins-and-outs of the program, Todd, so couldn't even begin to answer regarding configuration, but FWIW I DL'ed my copy of 0.11.2 sometime in early April of this year, IIRC.

You could rename the INI to something else then reinstall and see if the new INI will work correctly.

Now that version 0.11.3 is on the way, I will remember your suggeston or just delete the main configuration file when prompted during the next installation. A complete re-installation was probably not necessary. Post Extras:       Pages: 1
