I'm trying to learn using sextant and finding position by stars with Virtual Sailor 7.
My first calculations attempt - sighting sun - failed horribly, off by 785 nm
Of course, it was some calculation error, but still, I'm wondering a few things.
What sight corrections do I need to make? Dip, refraction, paralax, semidiameter? Are all of those simulated in VS to get correct Ho?
Also, since I red in one tutorial in this forum that VS GMT clock is off by +44 minutes, I always minus 44 minutes from my sighting GMT time.
And I'm using Nautical Almanac 2011 (of course, date is set correctly in VS).
Apart from these questions, is there anything else to know? Maybe there is some kind of tutorial with examples?
Thanks in advance!
