Greetings to you all, I am a physicist and sailor, and have been long fascinated by celestial navigation. I have studied the related chapters on Bowditch’s American Practical Navigator, understand well the theory behind it, and I am able to do the sight-reduction exercises with no difficulties.
However, I have never taken a sight. I would like to take advantage of this period where we are stuck at home to practice some sight reductions from home.
I live in a place where I cannot see the horizon. However, I can make an artificial one with a pan with a dark bottom filled with water (I have tried, and I can see in it a clear, beautiful reflection of the Moon), and I plan to purchase a sextant to practice sights with this artificial horizon.
Do you have any suggestion of a sextant model (new or second-hand) that I could purchase to this purpose? I am not looking for a very high-quality one, but for a model that is good enough to reproduce my correct position with these sights with a reasonable accuracty, i.e., a precision good enough to convince me that I am not getting that position by luck . In other words, I would like to see and be convinced that the sight reduction is working!
Also, given a suggested model, with what accuracy do you expect that it can reproduce my position with such an artificial horizon?
Thank you for you help!
