[Kstars-devel] Stars in KStars Lite

[Jasem Mutlaq]

Hi Artem,

Excellent work! I just tested it on my Samsung S5 and it works great!
Panning and zooming is smooth, great job!

1. I'm not sure, I did a git blame and it seems it was added by Akarsh, so
any ideas Akarsh?
2. Tycho-2 is expected as an addon. USNO "support" should be there but it
will not be offered as addon to KStars Lite (has to be done manually by
users for now).
3. Akarsh? I also think the struct needs to be documented in Doxygen as
well.

Regards,
Jasem
