Components of Astrology

In the world, in every place, the sun rise is at different time and the time told differs at every place and by one degree of longitude it makes a difference of 4 min.

Actual time or Ishtakal :- 

The real time at that place, where the native is born is known as ishtkal. By taking out the difference of time from the time zone to that place we can calculate the Actual time of birth. 

It is also known as local time the Ishtakal is taken out. For that, it is necessary to know the time of birth. The time of birth (as per Zonal time)and the time according to the Sun at that particular place of birth i.e. longitude and latitude.

RETROGRADE PLANETS
This is only a visionary phenomenon as this occurs due to different speeds of the planets in relation to the earth. The effects on a natal chart are due to fixed angular position of planets with reference to a particular place on the earth for a particular time, natal or transit.

Many texts has been written in this issue, and most of them are nicely backed by examples, logic and convincing arguments. As far as retro gradation is concern, except Moon, Venus and mercury, whichever planet comes from 150 degree to 210 degree from sun are retrograded, and Sun cover 1 house in one month. Which clearly means more then 33% of world population must have at least one planet retrograded in his or her horoscope, but by taking one or two thousands examples does not cover 0.00001% of survey. But such thing has been made a lot of panic in public and excuse for an astrologer due to which, he can escape from his wrong analysis.

Question Chart or Horary Astrology. 
The Question or Prashna Chart is made for specific queries at a particular time for those natives who do not possess a natal chart. The essential condition for effectiveness of the Question chart is that the seeker approaches an astrologer, when he is impelled by his inner self for seeking astrological help for a specific query, the chart has to be made on the basis of that time. Or can say a complete chart like the birth chart of the time of query is erected. Though there are variety of books or translations of classical works like Tajak Neelkanthi giving clues for analysing Question charts. There is a lot of books on it which helps any one to learn it.

Middle point of the house
The rising degree in the ascendant is treated as the middle point of the house, though some Text also says that rising degree of ascendant as the beginning point of the house. But we find it as middle point of ascendant.
