I have worked a sight by the Ageton Classic method and am impressed at how quick and easy it is. It is certainly a big improvement on Ageton 1938. I was stuck briefly because I could not find a B value of 17549 but then realised that if the table is read upwards the A and B values reverse. Hc differed from the app value by 0.4'.
Someone mused about why this method was not discovered back in the days when it really mattered. It probably required the fresh mind of someone who had the time to think about it and who did not rely on astro to put food on the table. To put it another way navigators in the pre-electronic era could not see the wood for the trees.
Someone else made the comment that collecting reduction methods is addictive. I can understand that (-; I found two volumes of 214 on ebay at a price I was prepared to pay. Then I checked the estimated cost of postage. This raised the price to > NZ$100 which I cannot justify. I will continues to look for sight reduction volumes but in many cases will have to use pdfs. I do not think that I can claim to have used a method unless it is with a paper document.
