Tables of Oblique Ascension

1
Hi there y'all

I am in need of tables of oblique ascension degree by degree for northern latitudes for primary directions. I have used those kindly posted on the "terra i cielo" website, in 5 degree increments, to make a pretty groovy graph from which i can interpolate good approximations for OA values, but my inner anal retentive demands more accuracy. However it is not so demanding that I feel drawn to calculate the data arithmetically by hand.

I use the Janus software, but I do like sitting out in the wilds to do astrology and hate being slumped in front of a computer for too long.

Does anyone have these tables and would be willing to share them? Conversely, I would be glad to share my A3 graphs if there is a good way to reproduce them.

Thanks in advance,

al Habashi

I wish someone would produce a book of these tables. You would really need a book to get them for each degree at different latitudes. I don?t know anywhere where they are currently available, but if someone else does know, I?d be interested too.

I calculate oblique ascension by subtracting ascensional difference from right ascension. But it would still be good to have tables

Let me get this straight. You want a table of oblique ascension for different latitudes side by side with the ascendant or LST (local sidereal time), right?

I have already written a simple program to calculate oblique ascensions in my computer (in MS Excel). Just tell me how to attach the file to send to you...

Hi Astrojin,

That?s very kind. I don?t know about al Habashi, but I?m not so interested in something that calculates the oblique ascension for particular charts, just tables of oblique ascension for different latitudes so that it is easier for students to learn how to calculate primary directions for themselves. Al Habashi mentioned the Cielo e Terra website (see link below) which has the tables for latitudes 40, 45, 50 and 55, and these are great ? but it would be better to have more detailed tables. Traditionally astrologers could buy a detailed set of these tables (though they would round them up to the nearest latitude). I don?t think there is anywhere that sells them nowadays because primary directions are much less fashionable.

Let?s say someone wanted to follow Lily?s instruction on calculating primary directions ? he gives tables of oblique ascension for latitude 53N. These are great for me because I live at that latitude, but I can?t apply his method of working for other latitudes because I don?t have the tables he was able to refer to.

Hi Deb,

Ok. I think I know what you and Habashi require. I have already run the computations for different latitudes. The computed table will have RAs (right ascensions) and OAs (obliques ascensions) for different longitudes (zodiacal degrees and signs) and latitudes (geographical latitudes).

Just tell me the range and increment of latitudes (and also the increment of longitudes) you require.

hi astrojin, hi deb

This is fantastic astrojin! Thank you very much, it will make my testing of Dorothean primaries so much easier!

What I would find most useful are values for OA for each whole degree of longitude from 01 to 360, for each degree of latitude from 30N to 60N. This would leave ony very small calculations for me, and even then only for fine tuning, as I increasingly turn to the algebuthar and its period rulers.

That's an awful lot of calculations though - too much astrojin?

Thank you once again for your kindness.

hi astrojin

sorry, i've had loads of techniocal problems down here. the e-mail address is correct, i don't know why you can't send me these kindly prepared tables, unless its because my yahoo account was full of offers of viagra and lotto wins.

please do try again astrojin

thanks

The e-mail still bounces back.

Anyway, the site Achernar gave is as good. You just need to run it for all latitudes that you are interested in!

I checked the calculations... They are identical to the table I produced. So I guess it's OK (unless both of us are wrong!!!)
