Everybody!
Okay, I think I'm done here as I cracked my own little 'mysteries':

1) My above message notes how to get better resolution.

2) The newer issue re. Stellarium?  -I found that http://www.stellarium.o
rg/
offers all the FREE versions we could ever use, including a free installa
ble
for even Windows-based systems.

3) The (default) real "scientific" packages were NOT -never in "Scientifi
c"
(SL), despite this really misleading (SL) name.  i.e.:  SL never held the

masses of excellent educational and truly scientific-based applications.
  i.e.: Digging in my archives I found that I had once (5 years ago?) loa
ded
an old Quantian distro and marveled at the wealth of really scientific
applications it offered.  Since my kids were so young then I didn't maint
ain
the distro.

The Resolution:
This week, after fully loading SL with extra packages and effectively
inventorying apps and testing much of it all, I now loaded...  the newest

version of perhaps SL's 'nemesis' system, Quantian (v 0.7.9.2), And,
although this version hasn't changed since March '06, I believe it is far

superior to SL in its offering of real "scientific" apps and opportunitie
s
for my kids.

So, "Scientific Linux" lab guys, how about pursuing and integrating real
scientific apps into your regular iso, let alone better versions of many 
of
the basic apps -or else change the name?  That's just my recommendation. 

(As it stands, I can't spend any more time w/ SL.)  Note: Dirk at Quantia
n
is not so active with the Quantian distro, as he has a regular job, but h
e
is very active in its wealth of topics and real scientific subject matter
. 
-"Hat's off" to Dirk!

(And we all have Stellarium on our PCs now.)
Thanks.
See ya!
