Stan and/or Greg,
I tried to use the "Current Year - 1900" and did not get results that matched either the Nautical Almanac or Stan K's posted example.
Perhaps I do not understand the process, For Stan's 30 Apr 201712-00-00UT example I did the following:
2017 -1900 = 117
So I entered 17.0430, and 12.0000 hit the "dot in the circle" key and the display reads Ho 37.154 which I understand as GHA Aries = 37° 51.4', hit the key again and the display reads d 14.409, dec Sun = 14° 40.9'N , hit the key again and the display reads H 0.419, GHA Sun 0° 41.9'
I get similar magnitude errors when comparing to the Daily pages.
Any ideas on what I'm doing wrong?
