Yes Martin, I have spent a lot of time on this issue. The problem with Alcyone's program is that it uses outdated ephemerides and only uses one variable to set all the previously mentioned constants and that is critical altitude. The results are different in some cases by months. Especially if the p...

Martin,

there's only one program that calculates the heliacal phases with respect to three basic parameters:

1) The magnitude of the planet or star.
2) The atmospheric extinction coefficient.
3) The difference in azimuths of the sun and the planet.

It's Porphyrius Magus 2 by Rumen Kolev.

I appreciate Robert Schmidt's work, but it is appropriate to quote his own words from 2016 (The So-Called 'Problem of House Division'): My own early translations in the ‘90’s were also provisional, and they were done relatively quickly as part of an overarching plan. It seemed to me that nobody had ...

Hi Martin, a very nice, practical and inspiring book. I bought it for myself as a Christmas present. I have argued for several years that Egyptian terms function correctly only in the sideric zodiac. That's why I'm glad you feel the same way.

Planetdance is an excellent program and deserves a larger primary direction module. It's good news that it's being planned for reconstruction.

ZET 9. This program can calculate primary directions according to Placidus. Zodiacal, mundo and under the field. Zodiacal directions counts without latitude. Classic conversion directions can't count. Placidus 7. I used Placidus 7 to check manual calculations when implementing the Morinus program's ...

For our example, Solar Fire will give us the right result, because he can do classical conversion directions. 12.5.2016 Classical conversion direction of the trine of Venus to MC. Janus 5.3 is a good program. Allows you to set up a classic conversion direction in a similar way as in Morinus. He can ...

Another program that does a lot in traditional astrology is Zeus. Currently still in progress its development and addition of other techniques. It is possible to obtain a license for one months, which is automatically renewed. The module of primary direction has a choice according to Placidus or Reg...

Of course, the several-day differences are not significant, but I want to follow a certain procedure so that the comparison is regular.

The module has only limited capabilities. Only three static keys, Zodiacal direction without or with latitude. A conversion direction is modern. The option of selecting a rectification step is advantageous. The choice of signifiers is limited to Asc and MC. The program on another page also allows th...

When I used the data from Martin and compiled the horoscope of Princess Victoria, I found a small difference in the value of the ascendant. Martin, I assume you used Solar Fire. If we use Morinus, for example, we get the value of the ascendant = 29°19'06 ''. The deviation is small, but can mean a di...

Hi Martin, Robert did the last upgrade of the program in 2017. Then it was taken over by Roberto Luporini and also Elias Molins. Currently, the primary directions module is part of the modified Astrolog 32 v.3.20 program. It is further developed by Roberto Luporini and James Ren. See pages: https://...
