Celestial Navigation Revisited

Here are the results of all 23 navigation stars that I shot from my position at N50° W0° in the English Channel. Most of the differences from Almanac data were positive which made me suspect another Index error, just like a real sextant. Applying this new correction drove the errors down to an average of 6 minutes of arc or 12 km. The largest error was 12.4', or just over a tenth of a degree. My tired eyes and SH3's low resolution seem to be good for about 10' or so...

The picture shows Procyon in the sights with a particularly good measurement!

Now we have two accurate sextants.
