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 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 I am stuck at home 😥 to practice some sight reductions from home.
Given that I live in a big city, I cannot see the horizon. However, I can make an artificial one with a pan with a dark bottom filled with water, 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!August 9, 2021 at 5:09 pm #10469JDavHoustonParticipant
I had an inexpensive Davis Mk. 3 until I accidentally knocked it off the table and stepped on it in the dark. It was hard to get sights though, as there were few stars actually visible.
