13 by Hareton The site with calculator is down. Does anyone have table of Oblique Ascention for 51 degree? I really need it. Quote Tue Feb 14, 2012 3:27 pm
14 by robhywolf Perhaps this can help? 1) With Google search for: "Celestial_philosophy_or_Genethliacal_ast.pdf" Underscores included. Otherwise try the following link: http://books.google.it/books/about/Cele ... edir_esc=y Donwload the PDF book, 1828 edition. Go to page 452: here there is the table of the oblique ascensions for latitude 51. Take care: the oblique ascensions depend on the obliquity. The book is quite old, and the table was reckoned with the value of 23? 28' (today is about 23? 26'). So, for the OAs we have a small error, anyway no more than 5'. For this reason the mathematical computation, according to the true obiquity, should be always advisable. 2) With Google search for: "Richard Fitzpatrick A modern Almagest" Donwload the PDF book. Starting from page 41 the tables of OA, up to the max latitudes. Both of them have some other merit. Roberto Quote Fri Feb 17, 2012 3:35 pm
15 by GR Hi all, Hareton, I sent you one via PM, let me know if you got it. robhywolf, thanks for the awesome link. I believe he also has a quite excellent book of Euclid's Elements on that site as well. To anyone, I've been toying with the idea of making a book of tables of oblique ascensions. Would anyone be interested in this? What other tables would be appropriate or desired? Gabe Quote Fri Feb 17, 2012 5:17 pm
16 by Hareton Someone send me them in PM, thanks. I will paste them for future seekers. The last column is OA.

17 by zoidsoft If you're going to use tables like this for primary directions at least make sure you are doing interpolation and stay away from extreme latitudes so that your results are at least within a year of being correct. Better yet use the formula: oblique ascension = Right ascension - c sin(c) = tan(geo.latitude) x tan(declination) C is the "correction factor". If we remember the rules for sides of an equation in trig, the Sin(C) becomes ArcSin as below: c = arcsin(tan(geo.latitude) x (tan(declination)) This works for directions of the ascendant, but Ptolemy said that it is not an accurate representation mathematically for planet to planet directions (unless one of them happens to be on the ascendant). Planets to the MC simply subtract their right ascensions for the difference applied to the key in years which is the simplest kind of direction. Planet to planet directions are another formula entirely (if you are following Placidus/Alchabitius method). The formula is much longer than these and involves many steps. Rumen Kolev did a nice mathematical simplification of Zoller's Alchabitius method in a paper back in 2003. Beware that primary directions are not simply a matter of getting the oblique ascensions of planets in most cases. Curtis Manwaring Zoidiasoft Technologies, LLC Quote Sat Feb 18, 2012 1:14 pm
18 by Hareton I live at 51'06, so it shouldn't be a problem. About planet to planet directions, I have seen one method that calculated somewhat middle value between RA and OA, is this correct? Quote Sat Feb 18, 2012 5:47 pm
19 by Ninneveh Does anyone known of an online source for generating Oblique Ascension tables? All the ones that were mentioned in previous posts seem to have disappeared. In addition, are there any in print books that have a complete set of Oblique Ascensions with all latitudes in them for handy reference? Quote Wed Oct 29, 2014 11:39 pm
