    Attached is an updated Ageton Classic checker.  The .exe has been changed to .exx for those using email that does not accept executable attachments, like gmail.  Just change it back to .exe and it will run.

     Jing,
    Welcome to NavList.
    You asked:
    "So on to my question. I've seen a few of the posts on this forum talk about calculators, and for completeness sake, I wanted to make sure I got as wide a range of opinions as possible. So here's my question: what calculators do you use for routine celestial navigation and why? Or do you use something else (a smart phone app, computer program, pen and paper only, etc), and why? "
    My favorite method for doing cel-nav is paper and pen using Greg Rudzinski's " Ageton Classic Sight Reduction Table".  Only 12 pages ( 6 back to back ) and you can do St Hilere intercepts, timed sights, great circle sailing, compass checks with amplutude or any other formula that uses sine and cosine.  Fast and fun - no need for electronics.
    I also have written several programs in Small Basic that I use when comparing a lot of ( other peoples ) sights.  My latest project was teaching myself Excel and now use the spreadsheet to do sight reduction.  But for fun I still like pen and paper.
    My calculator is the TI-30Xa.  Like Bill, I think it is fast and reliable.  No solar power but after 10 years of using it the thing just keeps on working.
    You asked why we use a method.  For me, if I just want quick answers then my calculator or spreadsheet is the fastest but for fun, to go outside and take a sextant sight, come inside and calculate altitude and azimuth then the hands-on feeling of pen and paper, looking up data in my alamanc and sine tables is my favorite.
    I am a retired pilot.  When I flew and needed to know my position then speed was important but now, hands-on fun is my way.
