This is a nice, practical explanation. For those looking for understanding of the trig proof, look up the "Inscribed Angle Theorum" on Wikipedia. I am often amazed at how brilliant those people were, hundreds of years ago. In this case a guy named Snellius put it together in the late 1500's.
Thanyou, one of the best i have seen. Great stuff, nice and simple. To enhance accuracy, and keep the instruction in line with standard practice, perhaps make the position lines go through the base of the object, which is standard practice when navigating on a nautical chart. The base, or dot at the base, represents the actual position of the object.
Hi Aus Navigation, that was great , I remember doing that at Australian Maritime College some 30 years ago and I love it. did not know about the last bit. Can you give a talk on Pelorus Compass !!!!!
I would like to see more examples of this. Perhaps make a worksheet with the answers. What I would REALLY like to see is exercises in reading a sextant. I have a book on Celestial Navigation, and it does have a section on ready the Degree Scale and the Venier Scale. However, they don't have many. Please make a work sheet with answers. Thanks.
I like your tutorials very much. The first part is great, exactly what I needed, but on the second part you went a little overboard. Show off. Love it.
Why subtract the observed angle from 90 degrees? That was not explained. I like the first method better, though plotting it would be a bit of a challenge without a protractor and taking a reading between three objects would be challenging when underway.
Thank you, this is exactly what i needed. Clear, and understandable for someone who is just learning about using a sextant!

Wonderful lesson 👌💙
Please continue and go ahead 💪🏼👌
All mariners will support you 🐬
Excellent. One small point: you can check the calculations and constructions by plotting an arc of position from the angle L1 L3.
Thank you very much.I was confused about this methods before.This video explained it quite nicely.

Hi can u tell how to measure the horizontal angle between the light houses using SEXTANT ????

Cool video, I am looking for more land based uses of sextant navigation if you have any more tips, tricks or methods.
Chris Yokum Thanks Chris. Again I'm sorry for the extensive delay in responding. I'll have a think about that and see what I can come up with.

Can you Solve for complementary angle 90° that is HSA is 180°
Really helpful video ! thanks mate
Station pointer ?
how did she get the 300 degrees?
Thank you, sir!
great. nicely explained

Love it.
nice explanation....thanks

This explains why the observed angle is subtracted from 90°.

very helpful...thanks alot
Outside the logic , the mathematics makes it harder
