[Xastir] feature request

[JD Erskine VA7OTC]

Hi All,

I'm not a programmer, even had trouble with some of the math though not the 
general concepts in an offshore/"celestial" navigation course I took a year 
and half ago. However, from that same course, quite a bit of celestial sphere 
position information is based on a the 360 degree circle starting at 
Greenwich and going around, I forget which way - I'll try to remember to 
check, past the Int'l Date Line to Greenwich again.

This allows for "easy" positional computation and of course little 'rules' 
for deciding whether one will add or subtract the bodies angle of difference 
from another body, (i.e. star, Sun,...) or Greenwich.

Maybe there could be a simple choice in the program setup or in the display. 
The choices would be as now for Atlantic Ocean use and another which just 
converted longitude from one reference to the other for Pacific Ocean 
centering.

Ideas are easy, eh? :{D I'll see what references I can dig up this week.
