Bennett's "The Complete On-Board Celestial Navigator" also lets you use your DR as your AP. http://www.amazon.com/exec/obidos/tg/detail/-/0071396578/qid%3D1077472470/ It is quite compact (176 pages for 2003-2007). Over the summer, George Huxtable pointed out its weaknesses. Bennett alludes to the same weaknesses (body close to horizon or directly overhead). I cannot say how It compares to Ageton's. Renee
