[Kstars-devel] 1e8 stars in KStars

[Jason Harris]

Akarsh!   that is so incredibly cool.  I cannot wait to try it out!

I think we may need to tweak how faint stars get drawn; they look  
pretty "muddy" at the moment...it's also interesting to see sharp  
"edges" in the colors of stars...my guess is that it's simply an  
artifact of the catalog itself.

regards,
Jason
