Hi Don1Reed, sorry for the delayed reply..
with regard to the Sextant, it currently works on the game default resolution of 1024x768. I've tried a 1280x1024 image but still have to sort out problems here.
(See image below) When taking a reading one has to horizontally rotate your screen view until the star is close to horizontal(X-Axis) screen centre. I had to do this as the vertical angle of the star changes with view rotation along the X-axis. the screen centre is the best(only viable) reference point in the game.
Next the sextant image is dragged out and placed left-off centre of the screen, with the top and bottom alignment markers just off screen.
After this you vertically rotate your view until the bottom of the screen aligns with the horizon. This has to be done as the game vertical screen scale is non-linear and the horizon is now the next reference point. You can now take a reading.
Also from what I've experienced so far The stars and constellations are in their correct positions with repect to time, so any star reading can be taken. Some body else here has already triangulated their position to 10nm accuracy so it's looking good so far.
The next image gives a visual idea of what is done above Plus the part that you were concerned about - angles above 60 degrees. The default game screen gives a vertical view angle of 60 Degrees, so if you want to 'shoot' 60-90 degrees one has to vertically rotate the scrren view to it's max.
This places the centre point of your screen at 90 degrees directly above you with +- 30 degree views either side of the vertical. I've found the scale here to be consistent with the horizontal view. You will now have the 60-90 degree view angles
Once I've sorted out all the different screen resolutions, I'll put a proper document together, as it is a bit lacking at the moment.
Thanks
