Introduction
PHD2 is the second generation of Craig Stark's original
PHD application.
PHD became a fixture of the amateur astronomy community with more than
a quarter million downloads. From its inception, it has
successfully embraced three seemingly conflicting objectives:
- For the beginning or casual imager, to deliver ease of use and good guiding performance "out of the box"
- For
the experienced imager, to deliver sophisticated guiding
algorithms, extensive options for tuning, and broad support for imaging
equipment
- For all users, to consistently exhibit a commercial level of quality while being available free of charge
In order to extend
PHD to more platforms and further expand its capabilities, Craig released his program to the open-source community, and
PHD2
is the direct result of that change. It has been
substantially restructured to make it more extensible and supportable
going forward. Now, after over 5 years of independent
development,
PHD2 includes a substantial number of new features and
refinements, many of which focus on helping you achieve better guiding
results.
Users of
PHD2 can be confident it will remain committed to the three objectives that made the original application so successful.
