One thing, using the script to set the sub location keeps me from seeing the sub lat & long. I get the ALT from Stellarium but have to do the rest of the math & table lookups to reduce the sights. It's satisfying to see the LOP's come together somewhere near my DR position (assuming I didn't make any errors in math or tables). I am also planning on looking at the game weather and only taking sights when the stars would be visible. several days of cloudy weather after the twists and turns dodging a destroyer might make for an interesting time relocating myself.
I have been using posplot.exe available at the
Navigation list for printing plotting sheets, and
gpaper.exe to print mercator paper for area maps. I think I'll be able to do most of my navigation on paper with these.
I also found an aircraft bubble sextant and my son and I have been using that to take star and sun sights at home. Last time we got within 2 miles of our home. It's an interesting learning experience for both of us.
