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.
