[Opensim-users] Stars in night sky in OpenSim are shapes rather than dots?

Thanks Tom,  I enjoyed that. Where are those Sun and Moon settings 
for star brightness?  Is it something in OpenSimDefaults.ini?

And thanks to Guy and Nebadon for the information.

I am using NVidia cards by the way... Nvidia Quadra 4500 1GB and 
Nvidia GTX 580 2GB.

I tried this again in a similar setting on a VCE region in OSGrid and 
on Second Life.. with the sun set to midnight, same size window, but 
using LL viewer for SL and Firestorm for OSGrid.

Second Life VCE region, Midnight, LL latest viewer

OSGrid/OpenSim VCE Region, Midnight, Firestorm latest OS viewer

I think I am setting exactly the same "shape" on each viewer, but the 
SL one is half the size of the OSGrid/OpenSim one.  is there an 
OpenSim release setting that is perhaps set up a bit too big?

Funnily enough.. I was just watching the Doctor Who episode with 
Vincent van Gogh this evening :-)  Starry Starry night
