prog. blocks all other progs from running correctly

[Jorge Blanco]

I am running windows 7 ultimate on a gateway netbook (quite smart) which has ever given any problem running programs in any combination. Stellarium almost completely takes up processing power and prevents any other prog from running smoothly.

HINT: any astron. prog without indication 0f startime and ecliptic coordinates also for stars is useless for seroius historical work. Please do it. Otherwise great prog but still too much of playing around touch.

1. For Stellarium need good graphics card with support OpenGL 2+. If your netbook support OpenGL lesser 1.4 then all "graphics" will be calculated by CPU. Please check drivers for your graphics card.

2. What you mean when say about startime?

[Jorge Blanco (domoracle)]

Hello Alexander (are you German? I am),

thank you for the fast response. I do not even know what open GL is and if
it is somehow on my machine. I'll check it out.

Well I don't know how deep you are into astronomy but star-time is very
important for the serious student of archeo-astronomy. It keeps track of
the position of the equinox point and is geared to the daily movement of
the stars instead of the sun. So knowing star-time and ecliptic position of
the sun on any specific day defines the relative position of earth with
reference to the stars. Very important. One can easily calculate star-time
for any date but is very handy to have it displayed with other times p.e.
UT. Also doing history I (maybe nobody else -:) ) always need ecliptic
coordinates of the stars but it would be too much to include that for only
one person. Thank you anyway for this program, it works fine and especially
the realistic simulation of light, atmosphere, etc. helps me in doing
studies of heliacal risings in the distant past.

If I correct understanding then you want display dates in JD or MJD also.

[Jorge Blanco (domoracle)]

well, that would be very helpful to have the JD additionally (even enter it
manually as an alternative to date-time). But in any case you could add, in
"ïnformation - displayed fields", a field showing Local Mean Star Time
(LMST) and JD. Another great thing would be to be able to take "shot"of the
current scenario and save it with one click for later reviewing. Not a
simple "screen shot"but a status report of all relevant data that allows
you to reconstruct the current situation. I don't know so far but can a
script do this job already? Well, we are gradually moving away from an easy
to use planetarium program to a more difficult research type thing. That
may be against your intentions.

Can you write use-cases for ecliptical coordinates?

[Jorge Blanco (domoracle)]

Well, I am probably not the typical Stellarium user. I am mainly interested
in historical (Babylonian) astronomy and those
ancients used the ecliptic coordinates almost exclusively. If you follow
the precession of the equinoxes through the ages
you might do it tracking Regulus (LUGAL) in ecliptic coordinates. That
gives you a fine pointer as to what precessional
"time"it is. So as I said, the feature might be uninteresting to the
average user, but to me it means a lot. Stellarium has
this nice feature that you can go back into the past for many thousands of
years (precessionally), Somme other good
progs only take to some 4000 BC (start of JD counting), which is not
enough. Thanks for your continued interest.

Jorge, can you check version 0.13.0 (ecliptic coordinates point)

[Alexander Wolf (alexwolf)]

JD can be shown as primary data at the bottom bar (and secondary through tooltip), plus Stellarium can show ecliptical coordinates for celestial objects. Original feature request is done IMHO. Jorge?

P.S. GMST/LMST can be implemented as main feature or additional for the Equation of Time plugin for example. In any case this feature request should be separate (maybe addition for #1106745?). Feature request for extends of the scripting engine should be filled a separate report also (this is interesting task IMHO).

[Jorge Blanco (domoracle)]

Thanks for note. Will check.

Hello!

I only now found this report, sorry. Its title does not reflect the aspects about history.

In the last weeks I finally implemented a more accurate precession solution for all people dealing with historical observations and their recreation. This also incudes accurate sidereal time display. It will be available in version 0.14. But it also exhibits the basic limitation of the commonly used VSOP87 planetary theory to times past -4000.

Is there anything missing now, or can we declare this closed?

[Jorge Blanco (domoracle)]

Great, thank you, for me it's ok/closed.

[gzotti (georg-zotti)]

For the record:

r7748 brought corrections to precession and ecliptic.
r7763 brought correct nutation and sidereal time display.
