People often ask me why natal chart calculation on my site shows incorrect data. That is, the planets, in their opinion, are not in the signs where they should be, and in general everything is different. Since the topic is raised often, and many people simply have not heard about sidereal astrology, which I use, I decided to write a special post and explain why some of my calculations do not agree with generally accepted astrology. Here you can express your opinion and ask questions.
Everyone knows about classical astrology of 12 zodiac signs because media made it very popular. Someone have heard of vedic astrology, which is based on Indian philosophy; It's actively used by people who are fond of yoga. But few people know about the sidereal astrological system, which is based on real astronomical data. Studying and practicing astrology, I became an adherent of the sidereal approach - its results impressed me very much. To show you visual differences between the tropical, vedic and sidereal systems, I made an infographic.
Article "Born under the sign of Ophiuchus and ignored by horoscopes: The dilemma of our time" by John Mosley of the Griffith Observatory, which was published in July 1988. In this article, he describes how the signs of the Zodiac differ from the constellations and tells where Ophiuchus came from.
Sooner or later anyone involved with astronomy has contact (or conflict) with astrology or someone interested in astrology. To a great extent the response from the astronomical and planetarium community has been defensive, denying the validity of astrology when asked. There have been some attempts to go on the offensive, such as the recent publication Objections to Astrology (Prometheus Books, 1975). However, such clearly antiastrology publications are probably only read by those who already are nonbelievers.
