Jagannatha Hora 7.6, which will be released in a few
days!

A new feature that I just finished adding is to enable user to define a
custom ayanamsa by *fixing* a star at a particular longitude. Almost
1000 stars are available to be chosen. The star you choose will always
be placed at the longitude you specify!

Instead of fixing Spica at the middle of Chitra, you can now fix Antares
at the start of Jyeshtha or Aldebaran in the middle of Rohini or Psi
Leonis at the beginning of Magha or Lesath at the beginning of Moola and
so on. The possibilities are endless.

If you select the custom star based ayanamsa, a dialog box will display
a list of nearly 1000 stars. They will be arranged in the order of
longitude, from 0Ar00 to 29Pi59. It will show the sidereal longitude and
latitude of the star on 2000 Jan 1 using Lahiri ayanamsa. This will give
you an idea of how off your ayanamsa will be from Lahiri depending on
the longitude you fix and also how away the star is from the ecliptic
(smaller the magnitude of latitude, closer to ecliptic). You can view
the list and choose a star and specify what you want its exact longitude
to be. Then all calculations will be based on that custom star based
ayanamsa!

Apart from stars like Spica (alpha virgonis), Antares (alpha scorpii),
Aldebaran (alpha taurii), Shaula (lambda scorpii) etc, it also includes
some clusters. For example, Galactic Center is included. So is "Great
Attractor" (cluster ACO 3627 near the Galacric Center).

This will enable those who want to experiment with different star based
ayanamsas to do some research.
