RealNav Mod - 1280x1024 Sextant image

Georg_Unterberg · 05-12-07, 02:51 PM

vanjast, thanks for explanation - I didn't know that.

I give you another series of 1280 measurements, now with star & sextant centered on screen:

at 10° lat: reading 10°
at 15° lat: reading 15°
at 20° lat: reading 20°
at 25° lat: reading 25,5°
at 30° lat: reading 31°
at 35° lat: reading ~36,7° (estimated decimals)
at 40° lat: reading ~42,3° (estimated decimals)

relative quiet sea, I got good readings.

the measurements are quite good in lower part of screen - getting a little bigger on higher part.
I could try to use this as offsets for the 1280x1024 sextant.

Again, everything above 45° is off limits, so you could navigate by only using stars with elevations <45° - something to consider.

Thanks, on 1280x1204 res, do you not get more than 45 Degrees vertical view angle ??

Another thing, do you know where I can get hold of that 1280x1024 utility - I'll have to try it out to get more accurate readings

I can look up and down like anyone else, but problem is the sextant keeps its screen position. It's not possible to "lock" the bottom scale on the horizon and then look up to shoot higher stars. I guess that's the way the dragging works - chronometer also stays on same screen position wherevever you go.

For higher res I use kegety's solution for WinXP SP2. you should follow this link if you want to try:
